INDIO, Calif. (AP) — When it first started in 1999, Coachella was a couple of stages and a dance tent. Tickets were $65. A few dusty stands sold hot dogs and Cokes. It was the end of grunge and the start of a new millennium, and it was all about the music. All for one weekend.

Now, tickets start at $375. Gourmet menus and VIP packages abound. And dozens of companies have hopped on the Coachella bandwagon, turning the music festival — now two back-to-back weekends — into a marketing hotspot. Adidas, Details magazine, Harper’s Bazaar and Lacoste are just some of the brands that host offsite festival events for stylish celebrity guests.
