I would have to agree with Phil Selway on drums. Seeing him play was when I first learned how hard the drums really were and the talent needed to play them. Anyone can play guitar....
But I digress.
Guitar - Lindsey Buckingham (most underrated guitarist in history), Jonny Greenwood a close runner up. Rick Mccollum, The Edge
Drums - Phil Selway, Larry Mullen Jr. and Neil Peart (you haven't lived til you seen his drum solo)
Bass - Adam Clayton, John Curley and Colin Greenwood
Piano - Tori Amos, Ben Folds
Vocals- Bono, Roy Orbison, Neil Diamond, Greg Dulli and the lead singer from DOVES (sorry can't think of his name right now)
