After shocking fans months ago with the news that its desert festival will span two weekends in 2012, Coachella confirmed with its lineup announcement Monday (January 9) that it is going big this year. Posted to the fest's Facebook page, the roster boasts Radiohead, The Black Keys and Dr. Dre with Snoop Dogg.

In response to last year's event selling out — a week after the 2011 lineup was announced — the festival is experimenting with featuring the same artists for two consecutive three-day weekends: April 13-15 and April 20-22.

The Black Keys, who performed last year, return to Friday night, this time getting top billing. Radiohead, Saturday's headliner, last graced Indio, California's Empire Polo Fields in 2004. This is the first booking for West Coast hip-hop legends Dre and Snoop, who will close out the main stage Sunday night.

Also headed to the desert are Florence and the Machine, Bon Iver, Swedish House Mafia, Afrojack, Kendrick Lamar, A$AP Rocky and the just-announced At the Drive-In reunion. Tickets for the 2012 Coachella Valley Music and Arts Festival go on sale Friday at 10 a.m. PT. The full lineup includes:
