Mardi Gras comes late this year – February 28, if you’re keeping track– but the closest most of us will get to New Orleans is this rare local appearance from Glen David Andrews, self-professed Crown Prince of Treme. Prince might not be an exaggeration, since the trombone-wielding MC comes from a dynasty of NOLA musical royalty. (His cousin Trombone Shorty opens the Newport Jazz Festival later this summer.) You might recognize the hyperactive bandleader from HBO’s Treme, or from the funerary second line he led at the end of Spike Lee’s Katrina documentary When The Levees Broke. Connecticut’s Funky Dawgz Brass Band open.
