I saw Sam Rivers play last night (Wed, 14th) at Vision Festival XI (http://www.visionfestival.org/)
I saw him once before play with this trio at the ICA in Boston a number of years ago. This time the first set was his big-band which I’ve only heard on CDs. In person you really can feel the power of this band.
 Check out Sam’s site (http://www.rivbea.com/) for his latest CD Aurora which they were selling at the show. It’s the latest from the big-band and is excellent.
