Girlpool, Chinatown. Formerly Los Angeles and now Philly electric guitar and bass duo of Harmony Tividad and Cleo Tucker sweeten their punk-rock sound on this plaintive, vulnerable video for their upcoming single. Opening for Alex G and Teen Suicide at PhilaMOCA on Tuesday.

George Pelecanos, The Martini Shot (Little Brown, $25) His first collection of short stories (and a novella) gives the Washington, D.C., tough-guy crime novelist and scriptwriter for The Wire and Treme opportunity to flesh out back stories of characters from his novels and plot a murder mystery set behind the scenes of a network cop drama.

Rihanna, Kanye West and Paul McCartney, "FourFiveSeconds." The second song released from the Yeezus-Macca meet-up, after the tender, Auto-Tuned "Only One" came out Dec. 31, brings Ri-Ri in for a charmingly off-hand strummer in which the cute Beatle is reduced to an unsinging acoustic guitarist.
