Coachella is the festival all others are measured against. Since 1999, Goldenvoice has staged it at the Empire Polo Club in Indio, and over two identical weekends each April the desert becomes the center of the music world. The lineup is famously genre-blind, pop and hip-hop headliners share the bill with reunited rock legends, breakout indie acts, and marquee DJs, but Coachella has always been about more than music: monumental art installations, the desert light, and a cultural gravity that pulls in fashion, film, and the entire internet for two weekends running. It's the anchor of Southern California's festival calendar and the reason the Coachella Valley is synonymous with live music worldwide.
