I concur that the show killed. I caught the Philly show and despite a sold out crowd, it was really good but not as great as Saturday's show which was indeed poorly attended, but it was a spirited presentation. Bob has been living in SF for a couple months now, I ran into him there in August and he was already there. I think he's just ready for the next phase of his life, and SF is a place that he's always wanted to live. I think honestly he's going to start to wind down from music and focus (eventually) on teaching. It's funny for as much as I really think DC was a good step for him, it also was necessary for him to leave too.
Oh, and Lady Gaga apparently was at Blowoff. Not sorry that I missed that one.
