It's pretty hard to argue the point that Radiohead is not the greatest progressive-art-rock group ever assembled. Here's an example why - A live performance of their track "The National Anthem" off of their 2000 album Kid A from back in '08 during a recorded "BBC Studios" live session. For all of the "techno-electro pop smoke, mirrors, bells & whistles" employed by Radiohead and their long-time producer and collaberat0r Nigel Goodrich in crafting any one of their LPs, they always seem to manage to sound just as good if not better when live.
