Last week, Radiohead nearly caused a nerd riot by sending out some vague e-mails or posting something cryptic on their blogs indicating there may or may not be a new Radiohead song. People went wild. And today, sure enough, there is “These Are My Twisted Words.” It is available for free download, which includes 18 pages of tracing patterns that create (I think) the silhouette of a dead tree. FOR FREE, you guys! And of course it’s a new Radiohead song, so that’s pretty special, as well.
