Live shows by New Orleans–based jam band Galactic aren’t so much concerts as they are a mini NOLA experience. The quintet’s lineup doesn’t include a regular vocalist, so members often outsource that responsibility to big-name talents like Macy Gray and Mavis Staples. Despite making music for more than two decades, Galactic’s energy hasn’t decreased on its latest release, 2015’s Into the Deep. The typical assumptions about jam bands don’t necessarily apply to this ensemble, however: It features a saxophonist and organist and, depending on the track, can vary in sound from funk to rock to R&B. Galactic has kicked it with The Roots and The Allman Brothers Band, preferring to back a lyricist because of its members’ aversion to writing lyrics. Galactic projects a brassy party vibe, elevating whoever is around it with its pep and table-dancing swing sound that dares you to stand still. Galactic performs with The Bright Light Social Hour at 8 p.m. at 9:30 Club, 815 V St. NW. $30. (202) 265-0930. 930.com.
