Friday-Sunday: Austin Reggae Fest at Auditorium Shores. Austin’s annual spring fling, which turns 25 this year, has adopted the slogan “What unity in the community sounds like,” which is appropriate. The fest draws one of the most diverse crowds we see in Austin each year; they show up for the feel-good grooves and the irie vibes. This year’s lineup features New Kingston and Kabaka Pyramind on Friday, Collie Buddz, Natalie Rize and Black Uhuru on Saturday, and the Wailers and Sister Nancy on Sunday. The event is the largest annual fundraiser for the Central Texas Food Bank, and a portion of each ticket sold goes to the local nonprofit. $15 Friday and Sunday, $20 Saturday. $45 for a three-day pass. Gates at 3 p.m. Friday, noon Saturday and Sunday. 900 West Riverside Drive. austinreggaefest.com. — D.S.S.
