At an unassuming 5-foot-2, Lauren Larson likes to startle. So don’t let her diminutive size fool you. Larson’s ferociously energetic guitar onslaught renders her a gargantuan guitar force. She’s just chock full of hair-flailing, guitar-wailing goodness. Larson fronts Austin-based Ume (pronounced ooo-may), a power trio whose other two members are Larson’s husband, Eric, on bass and Rachel Furhrer on drums.
