Jordison is a very good drummer, not very Technical, but fast as hell and still on point. Also I like Mike Portnoy a lot, and Derrek Roddy, saw him on drummers festival here in Hannover, amazing. he has to have dislocated feet or something.
Freddrik Andersson is a blast, too. very good guy.
to be a little out of metal, the one who kicks everyones ass still Charlie Antolini. he was on this Festival, too. this guy plays Blast beats for about 300 Jears now. and Ive never seen anyone playing stupid Paradiddels on 280 bpm, with a big smile and without getting any trouble. absolut killer this guy. and I recommend the link in my Sig, very good impro solo from a guy from Germany. have a look.
