I downloaded the Boston show. Comments:
Good musically. Really energetic with some fantastic instrumental work from him and his band.
The recording's pretty good as well, the bass is clearly audible.
It's pretty quiet though, I had to turn the volume all the way up to hear it clearly. I can set iTunes to automatically play it louder than everything else at least, so I won't have to adjust the volume everytime a song from it comes up on shuffle. Overall pretty good.
