The Record Company's story is a well-known one: a trio of musicians grit it out on their own for years in bars and clubs, join forces in LA, set up some microphones in a living room, and cut an album that turns their world upside down. The trio bring their American rock show to the Lowell Summer Music Series, Boardinghouse Park, 40 French St., Lowell. Tickets $34 in advance, $40 day of show.
