Record store employees love sharing music. It's the reason they endure dismal pay, endless alphabetizing, and an incessant stream of queries about whether those 45 adapters are actually earrings. The opportunity to champion little-known new releases and cult classics for inquisitive customers is vindication for record nerds. (Pilfering new arrivals is nice, too.) San Francisco touts many record shops, but Amoeba Music stands out for its selection's breadth, size, and turnover. Once a year, Amoebapalooza gives another chance for its clerks to share music, only this time they actually make it themselves, onstage. Employee bands, impromptu cover acts, and general record-head revelry is guaranteed, so mourn your aborted plans for a weed dispensary and relish the joy of sharing music with Amoeba's most knowledgeable clerks.
