Possessed of a delicate yet powerful voice, indie folk singer Laura Marling was only 16 when she first started gaining notice in 2007, and she still sounds far beyond her years on her addictive third album, "A Creature I Don't Know." Marling, who is occasionally reminiscent of Joni Mitchell, sounds lovely backed by banjo, brushed percussion and strings, but it's when she gets a little more sinister on electric-backed songs such as "The Beast" that she really shines. The Ford Amphitheatre, 2580 Cahuenga Blvd. East, Hollywood. 8 p.m. Sun. $35. http://www.fordtheatres.org.
