Wavves, with The Pharmacy, Broken Nobles. Neumos, 925 E. Pike St., 709-9467. 8 p.m. $12. Nathan Williams of Wavves spent 2009 getting into brawls everywhere from New York to Australia with doormen, his own bandmates, and someone from the Black Lips. He reached his nadir during a notorious onstage meltdown at a festival in Barcelona, where he got into a spat with his drummer (who quit the band), insulted his audience, and got booed off stage. (He later blamed the incident on a nasty little cocktail of Valium and ecstasy). For now, the 24-year-old Williams has a band -- if not his act -- together; he has a new bassist and drummer, both formerly of the late Jay Reatard's band, and released the third Wavves record, King of the Beach, this month. King is Wavves' cleanest effort to date; the lead single, "Post Acid," is as invigorating as a splash of water in the face the morning after a wild night (or year). ERIN K. THOMPSON
Emily Wells, with Anomie Bell. Triple Door, 216 Union St., 838-4333. 7:30 p.m. $12. All ages. With looping pedals and her violin, Emily Wells composes big songs that can be performed by one person. Hip hop has been as influential on Wells as classical, but while she may have Vivaldi dropping steamers in his grave, she's come under far more fire for the hip hop part. A controversial cover of Notorious B.I.G.'s "Juicy" attracted scorn from people who accused Wells, a white, classically-trained violinist, of appropriating a culture not her own. In Wells' own music, the hip hop influence is more subtle, but her album, The Symphonies: Dreams Memories & Parties, is an exploration of classical and folk music with hip hop production. If only she and Black Violin -- two violinists and a DJ who perform hip hop on violin -- could get together, maybe classical music will experience a comeback. SARA BRICKNER
