I saw Soulfly at Ozzfest, a few years ago. That prick who used to be in Machine Head was with them, and for some reason he had done his hair so it looked like he had a fucking pineapple sat on his shoulders. He just sort of leaped around with his Flying V round his ankles, gurning. What a bell-end
They were shit. Just play Chaos AD, but put a bag of sugar on the record to slow it down, then "play" some down-tuned boingy guitar sounds over the top of them, whilst sawing your balls off with a rusty hacksaw. That ought to sound exactly like Soulfly.
Oh, and the most important thing about Soulfly to remember is that they are totally "Lost in Shoooooooow-biz". Max is a big rock-star, hugely important. Yeah, A-list. Like Robb "I look up to Dan Spitz, literally" Flynn. Totally up their own arse.
Ah, that's better, glad I got that off my chest!
