On mariopavone.com (linked below), this three-night residency is described as "a mini-festival celebrating bassist/composer Mario Pavone's 50th year in music."
I heard the Street Songs band live last month and it was excellent. Considering taking a drive down for the Saturday performance with Eskelin, Michael Pavone and Gerald Cleaver.
On July 16, the Mario Pavone Nonet has a gig in New Haven that's one of the stops in a Street Songs / Accordion Project tour in Connecticut. Several posts about the New Haven gig that used to be in this thread have instead been quoted in a new thread about that tour, here.
