The annual parade of fashionable waifs and the waifishly fashionable known as the Coachella Valley Music and Arts Festival kicks off this weekend on the manicured polo fields of Indio that cut through an otherwise barren part of California. Event organisers have released the timetables for the three day event, and along with the usual head-scratching dilemma of bands you’d like to see clashing, they’ve managed to slip in a couple of surprises that they’ve somehow managed to keep really, really quiet. Along with headliners, the reunited OutKast, British heavyweights Muse, and Canadian darlings The Arcade Fire, you’ll notice a couple of names not seen on the posters prior to now in the legendary Pixies along with Stroker, Julian Casablancas.
