With the 2010 edition of the Coachella Valley Music and Arts Festival scheduled to get underway a little less than five months from now, we are finally starting to get an idea of what the lineup will look like.

According to a source with knowledge of the festival’s plans, Muse will serve as a headliner for the Indio, CA event, set to take place from April 16-18. This will mark the British outfit’s first appearance at Coachella since 2004 and will come amidst what will likely be a summer chock-full of tour dates in support of the band’s most recent effort, The Resistance.

A separate source confirms that both Hot Chip and The xx will make room in their recently announced U.S. tour and also appear. These latest additions join Devo, Craze & Klever, and As Tall As Lions, all of which have been previously confirmed by other Internet outlets.

Keeping the fun going, Vampire Weekend, Phoenix, The Avett Brothers, and Pavement are all heavily rumored, while Tegan & Sara, Spacemen 3, Pretty Lights, Cornelious, and Imogen Heap are among the others currently appearing on our Coachella Outlook page.

An official lineup announcement is expected to come in late January. Buckle up… the fun is only getting started!
