Tia Fuller, former saxophonist in Beyoncé’s band and now a professor in the Ensemble Department at Berklee College of Music, found herself back on stage the other night. Fuller organized a sold-out show by the Bruno Mars Ensemble, a collection of Berklee students playing 15 of the performer’s biggest hits. (The evening featured guest performances by rappers Ella Moore and Larry Contreras.) The show closed with an encore of Beyoncé’s “Formation” performed by Amber Kiner alongside dancers from Boston Conservatory at Berklee. . . . Heads-up: Jon Auer of the Posies (and, for a time, the reconstituted Big Star) is playing at the Burren on Sunday, and the Shellye Valauskas Experience will be there, too, playing songs from their new album, “History of Panic,” which features contributions from Auer, Shellye’s brother Ed Valauskas from Q Division, Dave Mattacks from Fairport Convention, and Abbie Barrett. Dig it.
