It’s the weight of it. Because it’s not like working with a band which would be boring to me when it’s just like four or five guys playing. I either wanted to do something very big or very small. If you look at the last track on my last few albums it’s just me and it’s quite small or otherwise it’s a cast of thousands. They were a great compromise in that way because of the weight they have. I mean they’re so loud. When we recorded them [laughs] it was shockingly loud. We’d go into the studio and… ha ha ha! We all had to wear earplugs. The first day we heard it – that brought new meaning to the phrase ‘guitar levels’. [Source]
