He appears on every album, but is the primary vocalist on Fire Walk With Us and With No Human Intervention. However, my personal favorite is Generator, even though Attila's only on one track. Don't forget Kali Yuga Bizarre, on which he does a couple tracks, but the other vocalist Yorga delivers one of the better vocal performances in extreme metal.
Fire Walk With Us eh. I take it that is a play off of a David Lynch film title. I will start there.
