Every music fan should vist the fine website maintained by the great Alex Gitlin: http://www.alexgitlin.com/bottom.htm Absolutley, one of the best sources for band links and info.

http://www.allmusic.com Artist discographies and track listings.

http://www.geocities.com/SunsetStrip/Palladium/9932/oly_indx.htm  An excellent source for musician bios.

I created and moderate Classic Rock Bass:  http://groups.yahoo.com/group/ClassicRockBass/

This group is dedicated to the BASS GUITAR and it's players form the 60s and 70s. It's about the superstars and the relitive unknowns. Sadly, more than a few are no longer whith us (John Entwistle, Gary Thain, Ronnie Lane, Felix Pappalardi, Phil Lynott, Greg Ridley, etc.).
Discussion includes their classic recordings, gear and current updates on the players who are still currently active. As well as member's gear and preferences.
It's for the fan as well as the musician (it's about Bass Guitar and it's players).
Though the group is loosely moderated, spam of any type will not be tolerated.
Welcome.
