Time was that college a capella groups existed mainly in nerdy hamlets of dorm rooms and YouTube channels, performing David Bowie and Of Montreal songs for the camera and each other. Glee
, of course, has changed all that, but the innate thrill of arranging a song for voices hasn’t been dulled—and probably never will. Napa hosts an annual A Capella Extravaganza
which pulls from the best cavalcades of California croon, and this year’s lineup is top-notch: The Scattertones, from UCLA, sing Lady Gaga’s “Telephone” and Kanye West’s “Stronger”; Naked Voices do “Superfreak” and “Bohemian Rhapsody”; and the UC Berkeley Men’s Octet do Seal’s “Kiss From a Rose” and who knows what else on Saturday, Feb. 5, at Napa High School. 2475 Jefferson St., Napa. 7:30pm. $20. 707.253.3705.
