GRR this is starting to be annoying, Portnoy is NOT very technical. The subdivisions he uses to play in awkward time signatures are always childish and pointless..... playing in 19/16 for the sake of it, which sounds fucking stupid, and is incredibly easy to do. I'd like to see the fucking mess portnoy would make of benighted, credence, the whole of damnation and any of the really quick double pedal passages, his top double pedal speed is pretty slow. Lopez has a beautiful style which mixes modern day death metal/rock with jazz/blues, all performed with a feel that reminds me sometimes of the late john bonham. Have you heard portnoy try and do this style of drumming, on the dream theater '5 years in a livetime' acoustic set or on most of transatlantic? It's terrible. OSI is the only thing Portnoy's done where he doesn't overplay terribly, and OSI fucking sucks.
