Put me in the 'Brad great' camp. He's right up there with Keith Jarrett, as far as I am concerned.
He only played one encore, because DC audiences, but it was a good'un -- the Beatles' "And I Love Her". But before his finale he explained that he was playing Bach, then a piece inspired by that piece by Bach, and with some improvisation mixed in. "...so this next piece will be another 'Bach/Me' pair..." (titters of laughter from the audience)
I was really hoping for Exit Music, though, that would've been nice.
