Radiohead Deliver Buoyant, Cathartic Headlining Set at Primavera

As the lights dimmed on the expansive open-air pitch of the Forum in Barcelona's San Adrián de Besós district, the cool Spanish night grew pregnant with expectation. But there were no chants of "Radiohead" erupting from the crowd. There were no odd yelps or screams or spontaneous hollers. Instead there was only darkness. And silence. It was less like a headline festival slot heading into its peak, and more the still unease you feel before the priest takes the alter for Sunday mass.
