The dA Center for the Arts in downtown Pomona is hosting possibly its most ambitious and well-attended exhibit ever, “Sounds of Pomona: Coming of Age in the Golden Era of Music, 1955-1975.” It’s a tribute to the city’s thriving music scene of the early rock era and its Latino-led bands who played at local dances. I’ve been to two of the events so far and they’ve been remarkably well-attended. I write about the effort in my Friday column.
