Yes, that Libertines show at the Black Cat was great. I believe it was around August 2003. Would have been cool to see Doherty w/ the band though - have to think he kicked it up a notch.
Another (sort of) - the reunited Stooges. I guess they haven't been too many places, but it'd be nice to get them to DC.
Sidenote to that - I was flipping through some book, I think Please Kill Me, and there was a story about the Stooges playing Constitution Hall in the early 70's. Who are the ad wizards who booked that?
