It was a good show. I stayed as long as I could, but the cold was too much for me. I did enjoy what I got.
Here's a description of the project from here site. I don't know who the actual musicians that night were. I enjoyed each of them.
Helen Gillet’s Wazozo Zorchestra
This is a sequal album to Wazozo’s first 2009 album “Newton
Circus.” Jon Gross (sousaphone), Doug Garrison (drums), Chris Kohl
(clarinet), and other suprise guests join Gregory Good (acoustic and
electric guitar), Daron Douglas (violin), Luke Brechtlesbauer (harp),
and Helen Gillet (cello, loop pedal, effects and voice) for an album of
all french chansons.
