None Better Than Gavin Harrison
I first became aware of Harrison when he was named the new drummer for Porcupine Tree. I had not heard of him, but took comfort in the words of the band's leader, Steven Wilson, that when the fans would first hear him playing they would understand why he was selected. And indeed we all did.
Harrison's style is a fantastic combination of impossible technique and ground-breaking creative styles that no one else plays.
Check him out on You Tube playing along with a prerecorded band track:
Gavin has published several books with accompanying DVDs on many of his innovative techniques. These are not for beginners to put it mildly. He also has a lot of you tube cuts of him giving short lessons on various topics.
But do check out this video. He doesn't ever go more than 20 seconds or so without doing something unexpected and extraordinary. And he never does anything not perfectly in service to the song.
