It was Matt Wilson, Bill Frisell, Jeff Lederer, Paul Sikivie and special guests playing Christmas tunes their own way. Joe Lovano played soprano sax on one. There was a 7 person choir on a couple. A male vocalist joined them on the last one. It was fun and a great show. I also felt more in the holiday spirit as a result.
It looks like there were different guests the next night, looking at the NY Times blog post below.
Drummer Matt Wilson fires up his Christmas Tree-O, first heard on an
enjoyable 2010 Palmetto CD, with reedist Jeff Lederer and bassist Paul
Sikivie—plus a very special guest in maverick guitarist Bill Frisell.
You'll hear a number of holiday favorites filtered through a
refreshingly edgy postbop lens.
