Rather than wait until Tuesday and compete with the Oscars, the Coachella fest organizers have made it official: Jack Johnson headlines Friday; Portishead is Saturday; and Waters performing "Dark Side of the Moon" is Sunday's closer. The poster is on the fest website. While it does point out that Waters is performing "Dark Side," it does not note if the great reggae poet Linton Kwesi Johnson will be reading or singing his politically charged works. 
If heat, exhaustion and sobriety are not an issue, here's my must-see list, provided I don't catch any of these acts before then:
FRIDAY
Rogue Wave, the Bees, Black Lips, Vampire Weekend, Jens Lekman, Minus the bear, Stars, Sharon Jones & the DapKings, the National, Raconteurs.
SATURDAY
New Young Pony Club, Bird & the Bee, MGMT, St,. Vincent, VHS or Beta, Mark Ronson, DeVotchKa, Hot Chip, Rilo Kiley, Cafe Tacuba, Portishead.
SUNDAY
Shout Out Louds, Manchester Orchestra, I'm From Barcelona, Black Mountain, Black Kids, Sia, Linton Kwesi Johnson, Gogol Bordello, My Morning Jacket
