"There’s loads of dark metal bands that I really like: the first Mayhem record, Darkthrone, people like that. But in the end, ‘Jerusalem’ is heavier and more powerful than any of the dark metal bands. It takes the best elements of Black Sabbath and then amplifies them even further. “It’s a record that I always used to put on before I went out and I’d listen to the whole thing because it was so emotive. It gave me loads of energy, even though it’s so slow and doomy. I love the fact that they released it all as one, hour-long song and how it was able to come out in that form. It means it’s never been vetted really. For me, it’s the best heavy guitar record ever made. “There’s something almost meditative about ‘Jerusalem’ and part of the band Sleep went on to form another band, OM, which is extremely meditative. So in Sleep, you can really hear the meditative atmosphere aspects of it, I like how hypnotic it is, that’s the reason I would always put it on. “Black Sabbath and Led Zeppelin were my entry points to metal, then I read a book called Lords of Chaos which I suppose a lot of people who are interested in learning about black metal have read. Then moving on and listening to the first Mayhem record, I thought it was pretty much like punk, but rather than just being snarling and aggressive, it goes beyond that and turns into something really evil. And I realised I liked the roughness of metal. “’Jerusalem’ is a flow. You’re hearing the band in the room as it happens and because it’s so unplanned it feels like a jam, which makes it much more subtle. They probably played through the whole hour a load of different times and it was probably different every single time. That’s what I love about it, when you hear the record you’re really getting the atmosphere they created at that time and they managed to capture that on record. There isn’t another record quite like it, and I also love all the records that the band members of Sleep made after it. “Josh from The Horrors and I went to see Sleep live and – although the guitarist was barely able to stand up because he was very, very drunk – it sounded amazing. People don’t realise how hard it is to make this music sound so good on stage. It’s something I aspire to and it’s an invaluable skill, right down to the way you position the mics on stage. For me the best metal is lo-fi, it’s highly sought after, getting music to be distorted in the right way. There’s such attention on the guitar in this record. Some guitarists play with a lot of pedals, but it can be really inspiring when you have a guitarist who can make music with very little and Sleep do that. “The first time I heard it was on The Horrors second American tour in 2008. We went to LA, and went to the place everyone goes to, which is Amoeba Records. I got a copy of Dopesmoker, which is the album after Jerusalem and that’s how I first heard ‘Jerusalem.’ But all I remember at first was thinking how awful the artwork was. It was really terrible"

"Many of the bands on this list are British. I was heavily influenced by British bands. At that particular time [Judas Priest, Black Sabbath, Led Zeppelin, etc. were releasing music] there was just an overwhelming amount of great music from across the Pond, from The Beatles forward. There was so much quantity and quality. All of these bands, in one way or another, either spurted out each other or inspired each other or created a split for somebody to go a different way. That sort of environment, using my own experience, with what happened in our small town with a handful of bands, it was a healthy level of respect and competition at the same time that kind of spurred the growth of all our bands. I'd assume it would be the same for a lot of these UK bands. To all metalheads, British Steel is one of the flagship records of all times. I dunno how many times I've been hanging with Dimebag [Darrell] and Vinnie Paul [from Pantera and Damageplan] and be cranking that record. You know, Dime always had a razor blade [pendant] around his neck and that's because of this record. These are some of the first riffs I started really learning how to play. K.K. Downing and Glenn Tipton are one of the all-time great dual guitars in metal, for sure, and Rob Halford is just the best. There's nobody like him."

"When I was about ten, I was given The Compact King Crimson on cassette tape and that’s what led me to “21st Century Schizoid Man.” This song is from In the Court of the Crimson King, which has the screaming face on the cover, and the face is inspired by the Arthur Janov book The Primal Scream. Primal Therapy: The Cure for Neurosis. “My Dad told me that at the time of the book and album there was a real fad for going out into nature and screaming guttural sounds. It became this zeitgeist self-help technique and I believe that’s what influenced the book, but essentially, it’s a guy having an existential meltdown and the song taps into that. “I think because I was young when I heard it, I didn’t appreciate this more complex meaning, and at the time I just appreciated the sheer aggression of the music. It was also the first time I’d ever heard those complicated time signatures and polyrhythms, as well as the combination of distorted guitar and saxophone. ""I hadn’t grown up on jazz, so I sort of thought it was for nerds, but when I heard this and heard the sax on the time signatures I was like ‘This is like jazz rock’. In the Court of the Crimson King is hailed by lots of people - like Shellac - as the first Math Rock or Post Rock record. They also invented heavy metal if you think about it, because they were doing riffs before Black Sabbath. “Our first album, Making Dens, is heavily indebted to King Crimson. We very much wore our influences on our sleeve in the beginning, and we had this approach of throwing everything including the kitchen sink at our songwriting. Whenever I listen to Making Dens, I hear the chaos of a band trying to sound like King Crimson. They’ve been a big influence for Mystery Jets."

"This is another record that I think Chris Bear might have found when we were twenty-one, twenty-two maybe, right before the band became Grizzly Bear. It’s a seven-minute, classic metal song with an almost Bowie-esque vocal delivery, it’s raging guitar music basically and I still love that kind of stuff. I had a deep metal phase as a kid, I loved Metallica and that kind of thing, but this is more in the Black Sabbath realm of heavy. “I’ve got a really strong memory of listening to this with Chris Bear and Chris Taylor. We had this phase between nineteen and twenty-two where we kept trying to be a band but it never really worked out. It didn’t happen until they’d started Grizzly Bear, I was the last guy to join, but when we were bonding over music around then it started to make sense we’d play together eventually. “We loved this song, it’s so classically heavy and cool and maybe it’s that, learning to appreciate music for what it is and not thinking about what it means, or if it’s moving you. It’s not cheesy or over the top, there’s a subtlety to it, it’s tasteful without trying or overthinking it. “We saw Danava play a few times in tiny clubs and they were incredible We saw lots of super-heavy music between 2004 and 2006 and being around New York was amazing for that, even Animal Collective were like that then, you’d see these crazy, heavy shows that were super-energetic and vibrant. “There’s not much documentation about this, but on our first couple of tours there was more of a heavier energy, musically it was much more improvised, frenetic and busy, closer to jazz. Our early live incarnation was somewhere between this and Elvin Jones, trying to channel this heavy energy. “It’s another one of those touchstones we talked about a lot when we were younger, not that it really made its way into our music very much, we never really made full on metal, but there’s occasional moments where that energy creeps in."

"I ended up with this record because it was at that point in my teenage years when I was swapping records with my mates at school. We were all a long-haired, Afghan coat-wearing gang into Black Sabbath, Deep Purple, Led Zeppelin and all those classic rock guitar bands. And Santana were almost amongst that; even when you go to albums like Abraxas and the early albums, they have a quite exotic kind of quality about them, so when Welcome came out, it was really rejected by the gang. It was like, ""Whoah! They've gone too far! What is this nonsense? We don't understand it!"" I got someone else's copy of it and I really started to sink into it. There are so many signposts in this record to the jazz world that has sustained me through the years. The first time I heard the words ""John Coltrane"" was through this record. Alice Coltrane is on the first track, which is this version of Dvořák's 'Going Home', which is adapted from his New World Symphony. It's like a classical piece played on a Mellotron. It's very dramatic and it's got nothing to do with rock music and more to do with that spiritual jazz that Alice Coltrane was knocking about. At that point, you couldn't give Alice Coltrane records away, and it's interesting that they didn't really gain currency until the late 90s. And then you've got people like Leon Thomas on the record, the guy who did the yodeling on Pharoah Sanders' records, which would lead you to his records. And John McLaughlin is on there, which would then lead you to The Mahavishnu Orchestra. Back then, you'd find these names on records and then when you were in the record shop, you'd find these names again and it all connected up like dot-to-dots. The concept of ""fusion"" throws up so many bad images because there's a load of shit there, but there's also so much good stuff as well. With this album, I opened the door expecting that rock guitar thing, but the sound of this record is fascinating: it has so much air in it and you can hear the sound of the room being pushed around. To me, this record is like audio sunshine and it transports me to some transcendental place."
