I posted links to some of the better stuff I've found in the Archive's "78 RPMs & Cylinder Recordings" collection here.
Don't miss The Live Music Archive (band list). My personal favorite band is there, so if it's been too long since they've been through town, I can always find a recent show, like this one, to listen to.
All the audio collections are listed here.
Dude — you are going to kill what little productivity I had in me...
THANKS!!!!
