Love 'em. Aenima is one of the best albums ever. They're brilliant. One of the best guitar players ever (very simple riffing but he always knows EXACTLY what to play, and some of their songs have 15-20 great riffs). Very interesting bassist and an insanely talented drummer. Very unique production, Maynard sounds good usually. I've posted my thoughts more on this thread:
