Vocalists- There are a lot of great lead singers, but one comes in mind for me in particular... I know I'm pretty much the only fan of them here because I'm about the only here who has ever heard of them, but the one of the lead singer/song writers of Jackopierce, Jack O'Neill, has one incredible voice. Bon Scott, the former vocalist of AC/DC (deceased), even though he doesn't sing, per-ce, he had an incredible voice because he could just scream pretty much through out the whole song and is very hard to impersonate because of that.
Other:
Scott Weiland- Formerly the Stone Temple Pilots but now with Velvet Revolver.
Keith Kane- Vertical Horizon. When VH started out as a singing songwriting duo, he had 50 % of the vocals on an album. He no longer sings lead vocals or writes songs anymore, but he still has an incredible voice.
Michael Stipe- R.E.M.
Robert Plant- Led Zeppelin
Rob Thomas- Matchbox Twenty
Davey Havok- AFI
Neil Young
Scott Stapp- Creed (Yes, you heard me. He may sound exactly like Eddie Vedder of Pearl Jam, but oh well.)
Kurt Cobain- Nirvana
Cary Pierce- Jackopierce (the other lead singer/writer)
Gordon Lightfoot
Dave Matthews
Brandon Boyd- Incubus
Dallas Smith- Default. He has a pretty good voice, but he honestly can't remember how to sing the songs live apparently.
Michael Hutchense- INXS
Drummers- Jose Pasillas- Incubus. He is just about probably the most underrated drummer on the face of the planet. I've honestly never heard before a style as unique and completely off the wall as his. Just listen to Pardon Me and Nowhere Fast. The Style is in a lot of Incubus songs, but in those two in particular. He doesn't get any of the credit he deserves. The same can be said about Jeremy Taggert- Our Lady Peace. He too has a unique style, indifferent from everyone else. Just listen to Starseed, Is Anybody Home, One Man Army, Life, Naveed, The Wonderful Future, and Bring Back The Sun because it mainly sticks out those songs.
Other:
Dave Grohl- Nirvana
Scott Philips- Creed (Yes, that's right, you heard me!)
Mike Cosgrove- Alien Ant Farm
John Dalmayan- System of A Down
Paul Doucette- Matchbox Twenty
John Bonham- Led Zeppelin
Keith Moon- The Who
Eric Kretz- Stone Temple Pilots
Carter Beauford- DMB
Guitarists-
Mike Einziger- Incubus
Daron Malakian- System of A Down
Dean DeLeo- Stone Temple Pilots
Angus Young- AC/DC. I know a lot of their songs sound alike, but some of his raunchy riffs helped create metal. I think anyways...
Jimmy Page- Led Zeppelin. Pretty damn amazing. Except for the only problem is, he, and the rest of Zepp, could be quite sloppy live. Also considering that he dubbed over a lot of rythym guitar parts in the studio which he couldn't do live obviously.
Bassists-
I may not know much about Bass, and it's also hard for me to hear in a lot of songs... But a lot of the basslines from the former bass player of Incubus, Dirk "Alex" Lance, stick out for me. Especially in 'Are You In?'.
Piano-
Rob Thomas- Matchbox Twenty
I'm honestly not too fond of Chris on the Piano...
