“Heroes” doesn’t equal the height of Low, but it’s an incredible album in its own way. Bowie created astonishing work in Berlin, and “Heroes” carved his name even deeper in the wall.

The opening track is snaky and serpentine, with Bowie spelunking down to the lower end of his range (“…gone wrong” slides to C#2, one of his deepest studio notes). “Heroes”‘ songs fall into two categories: the ones that make sense on their own, the the ones that make sense as part of “Heroes”. This is one of the former.

By contrast, track 2, “Joe the Lion”, is the latter. I can’t listen to it without the rest of the album: it sounds agitated and broken and gives the listener no relief at the end. But it does provide effective contrast for the krautrock-infused nostalgia of the next track: it’s like driving over a broken road, which changes to smooth blacktop.

The title song is the obligatory classic, which has survived overplay through massive sonic depth. There’s much to discover inside “Heroes”, between Carlos Alomar’s fill-in lines and Brian Eno’s electronic squawks. The song’s like an infinitely unfolding sheet of paper, containing yet more scribbles inside each unfurled fold. The lyrics are broad, and on the page sound faintly mocking, although no trace of this comes through on the record.

Functional harmonists describe music as a journey made of chords. When you listen to the tonic chord containing the key signature, you’re at home (in the Beatles’ “Yellow Submarine” this chord underlines “in the town…”). The subdominant chord is like leaving home to go on a journey (“…where I was born…”), the dominant chord is like arriving at your destination (“…lived a man…”) and then you might go home again back to the tonic (“…who sailed to sea.”).

Maybe my ear is bad, but little of “Heroes” makes sense when analysed in this fashion. There’s nothing that sounds like home, or a journey, or a destination. Notes swirl like squid ink, sometimes coagulating into chords, more often becoming pure texture. Even interesting. The album’s explorative nature is irresistable, even when it leaves the listener behind.

“V-2 Schneider” opens with air-tattered wailing, reminiscent of London during the blitz. The V-2s (German “Vergeltungswaffe”, “Retribution Weapon”) were long-range ballistic missiles, fired across the English channel at London, where they killed an average of two limeys per missile. The other side of the story was the 12,000 forced laborers who died in the production of the missiles. As with many purported Nazi superweapons, the V-2 was far more lethal to its builders than its targets. “Schneider” is “Florian Schneider-Esleben”, one of the founders of Kraftwerk: Bowie finally removed the letter c from his covert krautrock borrowings, making them overt.

“Sense of Doubt” is very dark, featuring a piano microphoned so that every note cleaves space with the power of an axe. A glittering synth line is introduced, as black as polished anthracite. I assumed this was Brian Eno’s work, but the song credits only Bowie. Much of the Berlin trilogy’s instrumental work was creating through procedural experimentation – the composer(s) drawing a card with instructions on it (“Use an unacceptable color”) and trying to attach a song to that scaffold. This isn’t unlike the process used by the Oulipo group to write books – although the Oulipists have yet to produce their Berlin Trilogy.

Traces of life stir in the shadow of this track. “Neukoln” is Bowie going “hey, remember when I used to play the saxophone?” and pairing it with yet more brutalist sonic architecture. His expressiveness seems like a plant weaving through cracked concrete.

The pattern of songs/ambience was used before in Low, which is part of why I prefer it. Even at its best, “Heroes” is retracing his own path, not forging a new one. The only difference is the final track, “The Secret Life of Arabia”, which is actually a song again. Maybe there is a journey to “Heroes”, but instead of in the chords, it’s in the songs. But there’s no sense of home when you follow those twinkling stars, just oddness and neurotic experiments. Or has home changed while you were away?

Keeping up with the Jones. After an artistically creative and personally devastating period in LA (full-cream milk, red peppers, and cocaine are a balanced diet, right?), Bowie went into hiding in Europe. Low is meant to meant to suggest “keeping a low profile”. He failed. Keeping a low profile would necessitate a bad album, and Low is simply unforgettable.

They “There’s old wave, there’s new wave, and there’s David Bowie” In a record store, they might say “there’s David Bowie, then there’s Low”. Nomimally the first of the so-caled “Berlin Trilogy” (despite parts of it being recorded in France), Low doesn’t quite sound like anything else he’s done.

Side A has songs, bending punk rock, art rock, . Bowie has seldom written better songs, and Eno’s technical wizardry makes the music seem otherwordly. This is most noticeable on “Speed of Life”, which has varispeeded delay that sounds like strobing flashes of light hitting the Hubble telescope from a distant cosmic object.

The songwriting is sparse and free. Entire songs are threaded together with simple ingredients: a single hook, or rhythm, or texture, but are all the more impactful for it. Lead single “Sound and Vision” has no words until the halfway point, and they’re just minimalistic automatism. No references to the Kabbalah or homosexuality. Just Bowie looking at blue light through his window, waiting for ideas.

“Be My Wife” surprises with familiarity, jarring you with a conventional verse/chorus pop song. Bowie was so good at being fake that there’s often a creepy, uncomfortable sense that he’s dropping the mask and momentarily sharing real feelings, knowing that nobody would ever know. The harmonica-driven instrumental “A New Career in a New Town” spins away the remaining grooves much as “Speed of Life” began them: in adventurous fashion.

Side A is an amazing achievement for Bowie, for Eno, and for rock. It is also Low’s worst side.

Side B deeply, profoundly well-realised, a haunting exploration of sound. It’s ambient music made jagged and broken, like a priceless Qianlong Vase smashed on the floor, allowing the viewer to find whatever beauty they may in the fragments.

People often refer to it as “the instrumental side”, which isn’t right, as only “Art Decade” lacks lyrics and vocals. But they’re brilliant, unforgettable pieces of music, and showcases just how much atmosphere Brian Eno could evoke with tape loops and a one-finger melody.

The dominant ambient piece is “Warszawa”, evoking a city of rust and memories, ancient fumes pouring from its skin. Futuristic Minimoog lines counterpoint church bells and religious chanting in a strange, brutal language from another world. It’s six minutes long: hermetic, cthonic, and almost impenetrable upon first listen. You have to peel it back like a palimpsest, and I’m still not sure I fully get it. David Bowie used to play this live. As a set opener, no less.

“Warszawa” was written by a four year old. Well, the first three notes, anyway. David needed to attend court to square away some matters from the Los Angeles fiasco, leaving Brian Eno to try and come up with something. Tony Visconti’s four year old son wandered into the studio, discovered the piano, and plonked out three notes – an A, a B, and a C. Suddenly inspired, Brian Eno dashed to the boy’s side and completed the melody. I don’t see Visconti’s son credited in the album booklet. The tyke should sue.

The album’s remaining pieces gently come down from this crescendo. “Art Decade” is chilly and still, its melodic ideas frozen like images under glass. “Weeping Wall” has very busy instrumentation, its elements sometimes clashing and other times working in harmony. “Subterraneans” is deep, slow, and forbidding. If the album was a day, this would be the deepest watch of the night.

There’s bonus tracks, too, if you get the right version of the album. “Some Are” seems like a marriage of the two halves of the album, while “All Saints” is extremely harsh – industrial ambient rock as corrosive as drain cleaner. I’ve heard rumors that “All Saints” was recorded a long time after Low, and indeed, it sounds very different in its production approach. You get a remixed version of “Sound and Vision”, which belongs in a bin.

Remember how people said that Judas Priest is old? Obsolete? Yesterday’s news? Irrelevent? Remember how this was thirty years ago?

Judas Priest is now so cartoonishly old that it’s difficult to know how to relate to them. They formed a year before the first Black Sabbath album, and their story encompasses every single rock cliche in the book. The young, scrappy upstarts (the first album), the creative prodigies (the next few), the complacency and artistic rot (the few after that), the inspirational rally (Screaming for Vengeance and Defenders of the Faith), the immediate collapse into self-parody (Turbo and Ram it Down), the even more inspirational comeback (Painkiller), the years in the wilderness following the loss of their singer (Jugulator and Demolition), the awkward picking up of pieces (Angel of Retribution), the self-indulgence Spinal Tappery (Nostradamus), and now we have their eighteenth album, Firepower, for which no storyline seems to apply.

The album’s firepower risks being overshadowed by the fireworks happening behind the scenes. Glen Tipton simultaneously revealed that a), he will not be touring with the band, and b), that he has Parkinsons, thus precipitating a). Additional controversy was provided by former guitarist KK Downing, who started rumors that Glen didn’t even play on the album. You know there’s a problem when your gay singer isn’t the most dramatic person in the band any more.

Firepower is hard to draw a bead on. On one hand it embraces nostalgia, mostly for the band’s Killing Machine and Painkiller sound. The title track and “Evil Never Dies” are both quite fast, and feature a downtuned approach to the angular E minor riffing that characterised Painkiller. But “No Surrender” and “Firepower” are quite consonant and radio-friendly, to the point of sounding like something from Rob Halford’s solo albums.

There’s no experimentation, and little blues (which is something I’ve always wanted Priest to revisit).

This contrast is found in the production job, which finds the band’s venerable early producer Tom Allom paired with veteran of the loudness wars Andy Sneap, who brickwalls Judas Priest relentlessly and leaves the listener little room to breathe among the overcompressed guitars. The overall package is entertaining and powerful, and even benefits a little from its fetishistic excess.

I wish it was shorter, but I also can’t pick which songs should be cut. They all have appealing moments, and good performances. Special attention must go to Halford, who sounds ridiculously good. The credits assure me the band still has a bass player, and I will take them at their word. Glen Tipton’s soloing (if it is really him) feels a little compromised. Probably the worst case is “Necromancer”, where he sounds like he’s wearing oven mitts. Ritchie Faulkner is more confident and poised, and strangely now one of the stronger points of the band.

As the final notes of “Sea of Red” fade like a bleached photograph, I’m left with a strange feeling: that this will never end. Judas Priest have always depicted fantasy in their lyrics and album covers. Perhaps the most fantastical was Stained Class, which depicted an android with a projectile embedded in its head. It’s not fantasy because of the android. It’s fantasy because it suggests Judas Priest can die.
