"This album has multiple covers and titles; it seems to be barely official. This is Coltrane’s last tour with Davis. He didn't want to go. His career had already started. He is sulky and petulant on these shows. His playing is edging towards the more raucous howl of his later revolutionary period. The night before this show he was booed in Paris; Miles would leave the stage during his solos. In Stockholm, eight minutes into ‘All Blues’, Coltrane does a remarkable thing. He hits a split note, a strangled harmonic that is clearly unintentional. He plays the same mistake a second time, and I would be prepared to venture that this second time was also accidental. Then he plays it a third time, then a fourth and fifth. It could be that he is going for the rule that if you play a mistake, then you should play it again and it becomes a part. You underline it and make it seem intentional. But it’s more than that. Coltrane is fascinated by this tortured phrase. He becomes obsessed with what his saxophone is doing, or rather what it isn't doing. He is going into a trance and circling the five notes again and again, sometimes with the smallest changes, sometimes repeated in different ways, but always this curious, odd, raspy note in the middle. The audience doesn't exist. It is just him and this one phrase. In total, he repeats the line 33 times. I just counted. The band goes with him as well, from initial worry to uncertainty and finally to outrageous confidence. It is both the dumbest and most intelligent piece of music I've ever heard, and I think about it all the time when I'm making records. It speaks about the power of repetition, the beauty of pure experimentation, and what you can get away with if you show confidence."

"Yeah, my mum bought it for Christmas. I must've been 18 at the time or something. I find it quite cool that my mum actually went into a record shop and asked for Metal Box by Public Image! There were only a few thousand made, so it was limited edition. But I was a huge PiL fan, I loved the Sex Pistols, Johnny Rotten/Lydon and when the Pistols split, everybody was waiting to see what he's going to come back with. Nobody could believe that he would return with this. They sounded like nothing you'd heard before. The first track, 'Albatross', is basically listening to Lydon screaming that he wishes he would die for ten minutes, or a junkyard having a nervous breakdown! The album has these metallic smashes and clangs, which I'd never heard in music before. This is considered one of the first post-punk albums, alongside the Siouxsie and the Banshees record, but before Metal Box, it would probably have been Pere Ubu's first album. From a UK fan's perspective, Banshees and PiL would have made the first post-punk records. We'd bought 'Death Disco' on 12"" records, but to buy an album in a canister, cut and mastered really loudly, bursting out of my speakers was something strange. These were not rock & roll songs, they didn't have a lot of dynamic to them at times either. They were danceable though, with a disco drumbeat, a dub reggae bass, playing Swan Lake on guitar, with Lydon screaming about his mother having cancer over the top of it and ending up on Top Of The Pops. That's avant-garde being taken into the fuckin' mainstream. To me that's very revolutionary and subversive. It was a real howl from the soul. Every time I listen to Metal Box, I remember what it was like to live in Britain in the late '70s when I was a teenager. It was a grey, damp, repressive country and that record reflects the state and times perfectly. It was a snapshot of the times."
