Bobby Bare Jr. is the son of country singer Bobby Bare, and his band Bare Jr. plays a hot southern rock that will leave you breathless Wednesday at the State Theatre (703-237-0300).

Thursday is the opening party for Art-O-Matic (202-661-7582), the huge annual art/music/film/etc. event that runs through Nov. 30 at the Waterfront (formerly the Waterside Mall) at 401 M St. SW. The list of happenings is long, so check it out at www.artomatic.org, but the opening Halloween party is the "don't miss" event. Danielle Howle has a great last name for an Oct. 31 show, but don't be scared. She plays her moving acoustic indie-rock Thursday at Jammin' Java (703-255-1566), along with Mississippi songwriter Claire Holley.
