"I don't really know what he's doing anymore musically and I haven't known for a long time, because it hasn't been his main focus for a long time, but Discreet Music is a very singular record. I'm just talking about side A: the other side is just something else. But you can play it on almost any kind of system and it works. It doesn't require hi-fi. I remember in 1978, around Christmas, my first wife and I went on a trip to Cadaqués in Spain, a place associated with Dali, and we rented a converted fisherman's cottage. It was three storeys high and an architect had worked on it, and what they'd done was they'd gutted the whole building top to bottom, and there was a staircase that ran from near the door up to the roof, which was a flat roof that you could sit on. And the floor seemed suspended. It was an amazing place. And we had a tape of this album and the kind of portable cassette player you used to have in the 70s, but you could put it on in the bottom part of the house, not even on full volume, and the room just filled. The music filtered through the whole space. I don't know any other music that could do that. He did other interesting ambient works and his early song records are good, but Discreet Music is such a singular piece. There really is nothing else like it that exists. It's just three notes. It's so simple. There's nothing to it, but it's completely musical."

"It's one of the classic records of all time, but I remember when this came out I wasn't particularly a Stevie Wonder fan. He'd done the singles and he was a Tamla pop artist really, wearing a suit, and I thought I'd got him labelled. But then this record came out and it was like his coming of age almost. It's like a small journey, listening to this album. It has a very positive beginning and ending, from side one right through to the last track. And that whole thing of here I am in New York, that wonderful idea of bringing in sound effects of street sounds that gave a different atmosphere and set the scene for what you're about to hear. I think most bands wanted to do that kind of thing but it was very easy for it to take over, so it was mostly left to the Pink Floyds of this world. But for somebody to do it just on the one track worked really well. And he played drums on this album, too. That was the weird thing, because when you listen to the drums it doesn't sound like a drummer. The things he plays aren't instinctive, so there's a different kind of musicality to what he's doing, and where it goes and where he puts things and where he hits the toms and where he does crashes and stuff like that. In some ways it was very brave of him, because let's face it he could've got any drummer to do it. But it gives it what I suppose these days you'd call an artisan quality, but I think of it as an earthy feel. Otherwise everything would be too perfect on this record. You have to have imperfection to give it character and personality. I think there's something about imperfection that puts you more in touch with what you're listening to, because you're not alienated by something that's unachievable. This record has that by the sack full"

"This comes from a place that keeps coming back into my life, which is Chicago. So many records from Chicago resonate in my Mancunian hellhole! When we were picking up Sun Ra records in the bargain bins for 50p with all the corners cut off, you'd go for the cover of the sleeves because on the back they'd show them playing these car parks somewhere with all this pageantry and all these weird electronic keyboards. And you'd be like, ""Oh! That looks really interesting!"" You'd put it on and it sounded like this odd, aged, Biblical music; like the Seven Tribes crossing the Sahara or something. It's very percussive – there huge sections where it's just percussion clattering away, and then you'd be hit by this kind of big band swing thing. And you'd be, ""Oh! That's really odd!"" and then there'd be an electric piano solo in the middle of that; it was just totally confusing! This was one of those records that sat around for a while and there'd be maybe one or two track that you went for. Gradually, the album would then open up for you. And then your friends would have another Sun Ra album and these things gathered together. There was a gig in Manchester in 1981, and it was Sun Ra with what must have been a 20-piece band and they had [saxophonist] John Gilmore and [singer/violinst] June Tyson in it – the classic version of the band, really – and it was like a three-hour concert. The epiphany that came with it was they did this enormous timeline that included music from the 1930s, which then went all the way through to freeform electronic wailing and synthesizer solos that went on for 15 minutes, as well as battles between trombones and really structured compositional things. A few years ago, it was Sun Ra's centenary and there was a festival in Liverpool and we put a band together to do a Sun Ra tribute. So we learnt a lot of stuff from the Impulse label records – the 50s Chicago stuff – and you can get all the music from the Smithsonian. We put in enough time to making it sound good and it was a really rewarding experience to live in that music for a while. [Saxophonist] Marshall Allen once stayed at my house. He saw all the instruments lying around and he says, ""Oh, you play?"" And I was like, ""Sort of"" because at that point, imposter syndrome kicks in, but he was like, ""Can you play two notes?"" and I'm going, ""Yeah, yeah"" and he said, ""Well, let's do it!"" We ended up setting up a recording session and we made an album in the evening, and then went out and had kebabs! But it's interesting how popular Sun Ra's records have become over time, because back then, they were practically giving them away."
