Fun at the Wiltern

MUSIC

Maybe no band’s name has been a more self-fulfilling prophesy than fun. The trio’s single “We Are Young” was a surprise hit of the year, built on piano-pop savvy and epic hooks. The rest of their catalog is fizzy, buzzy and livened up with au courant electronics, and they play a victory lap stand this week. The Wiltern, 3790 Wilshire Blvd., L.A. 7:30 p.m. Fri.-Sun., $25. wiltern.com.
