I went to this festival in Barcelona for the first time last year and had a great time, so i'm planning to go again next year. First bands have just been released (and there was a lot of crossover with Coachella last year, so expect to see a few of these in Indio too)
The tickets are very cheap (80 euro for 3 days) and they even take paypal.
