Lake Street Dive/The Congress

Lounge jazz vocals laid across Americana chord progressions and riffs: Well, that’s at least a start when it comes to describing the new-meets-old blend of musical traditions in Lake Street Dive. The Boston band has been buzzing around the Northeast for about a decade, and their 2014 album, Bad Self Portraits, is beginning to earn them some serious widespread acclaim. Fronted by the dynamic Rachael Price, this band boasts but three instruments (upright bass, guitar, drums), but somehow manages to sound like a waterfall of layered sound. Apart from their studio stuff, we might point you to the KEXP and WFUV sets floating around on Youtube. To wit, this band commands a helluva stage presences, and tunes like “You Go Down Smooth” and “Bad Self Portraits” will have the Beachland rockin’ tonight. (Sandy)
