The amphitheater formerly known as Great Woods, at the edge of a large conservation area in Mansfield, Mass., is now called the Comcast Center. Given that the headliner there on Tuesday night was Radiohead — a band that famously dropped its major corporate label, once touted Naomi Klein’s No Logo, and is now teaming up with the grassroots climate activists of — the name dripped a fitting irony.

Not that Radiohead has ever had a problem with contradiction or cognitive dissonance. Arty, cerebral darlings of serious post-boomer, meta-critical rock, they’ve made a career and some pretty great music out of it — doing their best to subvert techno-consumer culture by its own devices for a good two decades.
