Fol Chen, a group of six pop chameleons from Los Angeles, have been making art-damaged music since 2009 on Sufjan Steven’s Asthmatic Kitty Label. With each release, they become more mainstream-focused, especially the third The False Alarms, which came out last month. Fol Chen plays the Black Cat tomorrow night. Today’s song of the day is the catchy track “I.O.U.” The song is some of the most accessible and catchy the band have ever been, building on the promise of their other great track, “In Ruins.”

Fol Chen play tomorrow with Valleys at the Black Cat. Tickets $12.
