Looking at this list, I think we should stick to released material, i.e live covers are out, as are fan performances, however wondrous they might be. I'd say that The Kleptones should be out also, as they're not covers.

It's bad enough trying to keep up with all the tribute albums and the (with all due respect) minor artists that we CAN'T ignore (Valentine, Soto) without getting into every band whose drummer once went "thud thud tisch"...

What does everyone else think?
