Indio - The Weeknd brought a raw emotional intimacy as he headlined the first night of the Coachella festival, where electronic music pioneer Jean-Michel Jarre lit up the California desert sky with lasers and calls to safeguard the environment. Packing 125 000 fashionably - or at least scantily - dressed fans onto the sun-baked site in Indio, Coachella has become the titan of music festivals and a global brand with a who's who of acts who play back-to-back weekends with identical line-ups.
