This year's Coachella lineup was announced at a press conference Monday in Mexico City (held there as a way of thanking the country's citizens for their annual support of the festival), and while Pink Floyd architect Roger Waters looks to be closing the festival with a Sunday headlining spot, performing the band's 1973 opus 'Dark Side of the Moon,' it's the first appearance in Indio for trip-hop masters Portishead that is the festival's coup.

The band, who will headline day two, has long appeared on the wish list of organizers Goldenvoice, but with the quartet taking a long hiatus, from 1999 to 2005, they have never been available or active in the festival's run. All that changed though with the announcement their third album -- and first studio work since 1997's eponymous album -- will be released this year. As of this moment, the date appears to be their first Stateside in a decade. The group recently previewed new material in their native UK at the All Tomorrow's Parties festival.

In fact, this year's lineup, at least the initial acts announced of the 125 that will make the trek to the desert April 25-27 of this year, features a return to the early Coachella days of dance music playing an integral part of the festival. Joining Portishead in Indio will be M.I.A., Justice, Kraftwerk -- whose 2004 headlining set in the Sahara Tent still ranks among the most crowded and anticipated in the dance tent's history -- Fatboy Slim, tag-team DJ superstars Sasha & Digweed, UNKLE, Junkie XL and Danny Tenaglia, another longtime Coachella holdout making his first appearance.

Meanwhile, holding up on the rock front are My Morning Jacket, Love & Rockets, Jack Johnson -- headlining Friday along with a reunited Verve -- the Raconteurs, Rilo Kiley, Death Cab for Cutie, the National, Madness, Swedish death metal stars Turbonegro, Vampire Weekend, the Breeders, Spiritualized, Autolux and Louis XIV.
