Rilo Kiley Music Group

There is a girl in a tank top who appears in the lyrics of "Smoke Detector," a backbeat-powered, beach party-worthy romp on "Under the Blacklight," the fourth album by the much-loved Los Angeles band Rilo Kiley. She is not wearing a bra, and she cries "Danger!" when she hits the dance floor. Jenny Lewis created this character. But she can't completely relate. "It's not me. I always wear a bra," said Lewis, the band's singer and principal songwriter.

When you title an album "More Adventurous," you'd better back it up or brace yourself for some bad jokes. The Los Angeles band Rilo Kiley slapped that target on its upcoming record, but they probably won't have to worry about the one-liners. The collection, due Aug. 17, has the feel of a breakthrough into a whole new level of accessibility.

The songs on Rilo Kiley's second album, "The Execution of All Things," are catchy and down-to-earth, but they also carry a hint of childhood mystery, with Jenny Lewis' voice and nursery rhyme passages suggesting that the adult struggles outlined in the songs are rooted in the deepest memories. So it somehow seems appropriate when the singer looks around the old-school Silver Lake coffee shop where she's having lunch and says her mother once was a waitress here.
