They were AWESOME.
Kim Deal's bass skills, up close and personal: AWESOME.
Black Francis' voice: AWESOME
Joey Santiago and David Lovering were also AWESOME, but we were on Kim's side, and drums obscure David's face, so the pics we have of them are quite limited. But if you're interested, see more of Trevor's excellent photos here.
Anyway, the awesomeness was in large part because I think they are getting along, and happy.
Even Joey Santiago smiled a couple of times. Really!
Terrific show. Well worth the $30 t-shirts (!) I know, I felt kind of like a sucker buying one, but it had a crab on it! And the band's gotta get paid, yo.
They were also offering "USB sticks" (or flashdrives) that you could buy after the show with video and recordings of the performance. I've never seen that before, but what a cool idea. I didn't get one, but then lo and behold, your friendly Bad Librarian posted how you can get an official and totally Pixies sanctioned live recording of Doolittle.
P.S. -- I wore my David J shirt because Black Francis is playing with David 12.08.2009 at the Echoplex in LA. I thought he might say something, but my big surprise instead was Kim Deal cheering at my shirt when they did their farewells after the last encore. Badass (Fender) bass players unite!
