Dr. Dre will close the 2012 edition of the annual Indio festival, to be held for the first time over consecutive weekends, the first April 13-15 and the second April 20-22. Headliners for the multi-weekend, six-day affair include rock acts the Black Keys, Radiohead and the Shins, as well hip-hop and dance acts Snoop Dogg, the Swedish House Mafia and Kaskade, among many others.

Tickets were initially sold for the 2012 festival nearly a year in advance of the event. Three-day passes went on sale via Coachella’s official site for one week in June. In prior years, tickets were not sold until the lineup had been revealed, and were sold via Ticketmaster. Tickets were once again priced at $269, not including service fees. Goldenvoice had earlier said that if tickets remained after the one-week presale, they would be made available once the lineup was announced.

Though Coachella will close with a double hip-hop pairing of Dr. Dre and Snoop Dogg on the two Sunday evenings, rock acts will get top billing the other nights. Bluesey rockers the Black Keys will anchor a Friday that will also feature singer-songwriter Cat Power, reggae legend Jimmy Cliff and psychedelic electronic act M83. Radiohead will close the festival’s Saturday evenings, with breakout indie star Bon Iver, reclusive indie rocker Jeff Mangum and noIse instrumentalists Godspeed You Black Emperor also on the bill.
