Radiohead fans should be used to being caught off guard. The rock band no stranger to bucking the system. In 2007, they gave a 10-day notice for the release of “In Rainbows” and if that wasn’t enough to shock their fans, Radiohead released it as a pay-what-you-want album. Four years later, they gave even less notice for their next album. “The Kings of Limbs” was announced five days before it was available for purchase. They managed to move nearly 400,000 copies on the band’s website alone.
