Prince was so beloved in the Bay Area that when he died in 2016, San Francisco City Hall was illuminated in the color most associated with the artist, purple. Today, the Oakland-based Purple Ones pay tribute to his music with its 12-piece band, which includes a full horn section. The group will perform on July 6 at 8 p.m. at Twin Pine Casino and Hotel in Middletown. Admission is $20. Find out more at twinpine.com.
