On the eve of its sixth year, North America’s biggest and best two-day music festival celebrates its existence with this fine look at the event from all angles. Working as an introduction to newcomers and a refresher for those who’ve attended in the past, Coachella handpicks some of the festival’s most colourful attendees, artists and best performances over the years from the likes of Radiohead, the Arcade Fire, Pixies, Björk, the White Stripes and the Flaming Lips, which confirm their highlight reel worth with Wayne Coyne’s bubble boy excursion into the crowd. Also included is a second disc with a selection of interviews with random bands, but unlike the first’s satisfying feature, disc two plays out like a slapdash footnote. (Goldenvoice/Epitaph)
