What were Radiohead like Del?
They were alright. Savages played before them and holyshit they were amazing. We (me and my daughter) have now been to 4 major festivals in 4 different countries. I'd have to say that (so far, Chile next year) Primavera was the best organized, the crowd and staff were brilliant, location fantastic, all very chill, but for the headliners there's just too many people, probably 100,000+. LCD Soundsystem were way better than Radiohead imo.
But, as with all festivals the real fun is at the smaller stages. Primavera has 7 stages so the variety is endless, plus you're in Barcelona!!!
