Nobody mentioning Colaiuta here. Too many underexposed lads here. And I forgot Porcaro...groove like nobody else. Also, no mention of Gadd or Weckl.
Portnoy another mystery. Odd meters, double bass fills...nothing crazy. Charlie Watts, remedial drumming at its best. Rock drumming is high school, guys I mention are top pros.
I like Bohnam, but his sound is more a mixing/recording thing. Any fat sounded reverb room, will give you a big sound. He did have some nice grooves though. A bit overrated, like Portnoy.
