The first thing I saw inside La Plaza de Cultura y Artes on Saturday afternoon was Brenton Wood’s zoot suit, a gray number paired with a black-and- white tie and wide-brimmed fedora. The dapper mannequin gave me some kind of sign (sorry, couldn’t resist) of what was to come. Stage outfits like Little Willie G.’s suit from Thee Midniters, flyers for shows like The Brat at The Vex in 1980, t-shirts repping Quetzal and Slowrider and a vinyl wall with everyone from The Premiers to Tierra to Alice Bag to Thee Sinseers. A Great Day in East L.A.: Celebrando the Eastside Sound is a multi-media exhibition that pulls together various tangents related to more than half a century of East Los Angeles music. It’s a thorough show that’s absolutely essential to see if you’re interested in L.A. music. The exhibition opened in late June at La Plaza de Cultures y Artes, across from Olvera Street, and is on view until August of 2026.
