After a two-year hiatus during the pandemic, Coachella roared back for the first of two weekends. The music festival’s lineup included Billie Eilish, Danny Elfman and The Weeknd. One of the many stages set up in the California desert is a perennial fan favorite: the Do LaB. Under the Do LaB’s 200-by 200-foot wide tent made of colorful, lightweight triangular fabrics held together with tension wires and cables, DJs spun pulsating beats and musicians serenaded with House, R&B and electronic music. Aerial dancers floated down from colorful fabrics.
