On Sunday afternoon, indie rock pioneers Superchunk hit Other Music, performing an acoustic set between sold-out shows during the weekend at Bowery Ballroom and Music Hall of Williamsburg. The group’s setlist included “Everything At Once,” a video of which appears above.

A line to enter the shop began wrapping around the corner of Lafayette Street and East 4th Street an hour in advance of the band’s 1 p.m. performance. The crowd was comprised of noticeably few Gen Y fans, who were largely outnumbered by die-hard, middle-aged rockers and a handful of flannel-clad toddlers. (“Are you excited for your first rock show?” one indie Dad asked his daughter.)

Performing sans bassist Laura Ballance, the trio—frontman Mac McCaughan, guitarist Jim Wilbur and drummer Jon Wurster—powered through seven songs. Included were “Slow Drip,” and “Digging for Something” from the band’s ninth studio album “Majesty Shredding,” out last week via Merge Records, the label founded by Ms. Ballance and Mr. McCaughan in 1989.

Other Music regularly pushes their CD shelves aside for in-store performances and special events. The shop hosts Maximum Balloon on Sept. 27 and Cursive’s Tim Kasher on Oct. 5.
