Stakes seem necessarily high when one of the biggest independent rock bands in the worlda Montreal eight-piece called Arcade Fireclimbs into two rented vans and drives across this country’s northern border to play two pre-primary election rallies 50 miles apart in North Carolina. That the band convinced Superchunkthe historical flagship of its label, Merge, and a band that plays once or twice a yearto join them for two dates is as astonishing. At one point during the run, Superchunk frontman Mac McCaughan said guitarist Jim Wilbur only agreed to play when he was told he’d have a Secret Service detail to himself.

Cheering under the mid-afternoon spring sun, the crowd didn’t seem to mind.
