When i think of amazing drumming, I think of Billy Cobham on 'Dawn,' Neil Peart and Dave Weckl at the Buddy Rich Memorial Concert, Joe Morrello on 'Take Five,' and Danny Carey on 'Lateralus.'
When I think of amazing vocals, I think of Freddie Mercury on everything ever, Layne Staley on the live/acoustic 'Nutshell,' and Hansi Kürsch on 'Another Holy War.'
When I think amazing guitar work, I think John McLaughlin on 'Awakening,' Steve Howe on 'Mood for a Day' and the Yessongs 'Starship Trooper,' Frank Zappa on 'Montana,' and Billy Corgan on 'Starla.'
When I think of amazing bass work, I think of Paul McCartney on 'A Day In the Life,' Chris Squire, Victor Wooten, Les Claypool, and Geddy Lee on pretty much everything.
When I think of amazing keyboards, I think of Rick Wakeman on 'Close to the Edge,' Ben Folds on 'Philosophy,' and John Evans on 'Thick as a Brick.'
There are, of course, countless more, but those are just a few.
