Yes, you can say that Radiohead’s an evolutionary band, but it’s been a pretty intra-species evolution, with fewer of the fits and jumps of someone like David Bowie or even the convolutions The Beatles had to make (along with everyone else) in a much shorter time frame. I mean, even the “new”/“experimental” stuff that Radiohead’s added to their alternative rock foundation over the last fifteen years isn’t anything that would be unrecognizable to smart musical audiences in 1993.
And you can listen to their new album at, as Khoi Vinh says, the speed of hype.
