St. Vincent will also play the Somerville Theatre

World Music/CRASHarts just announced a May 19 show at the Davis Square venue by St. Vincent, aka singer-songwriter-multi-instrumentalist Annie Clark, a Berklee grad whose 2007 debut "Marry Me" was an indie fave. Her rich pop sound reminds of Sufjan Stevens; she played in his touring band, as well as  Polyphonic Spree and Glenn Branca's Guitar Orchestra. Her new album, "Actor," is due May 5, and Clark co-produced with John Congleton (Modest Mouse, Polyphonic Spree). So don't be surprised if she blows up big. Well, indie big. Tickets go on sale March 20 at 10 a.m. at (617) 876-4275 or online.
