You'll love it! There is always a lot of magic felt within groups that are playing something that is fresh and stimulating to them, and having ample opportunity to flex their creative muscles. You don't get that with the boy bands that basically reproduce their albums night after night
I don't know how new the music feels to them after their 25 year hiatus, but they also mixed things up a little bit from their original albums, and they convinced at least me that the energy and enthusiasm was still there
I also heard Medeski, Martin, Scofield, and Wood shortly before that and even though I'm a big fan, I didn't quite feel the same way... They sounded a little tired.
