On “Lotus Flower,” the closest Radiohead gets to a single on its new album “The King of Limbs,” frontman Thom Yorke declares, “I will slip into the groove.” But it’s perhaps the bleakest, slightest groove in existence – and the song is the high point of the eight-song, 37-minute album from the groundbreaking British rockers. In most places, “The King of Limbs” leans electronic in a way that mimics Yorke’s 2006 solo jaunt “The Eraser” more than the band’s 2000 masterpiece “Kid A;” while in others, such as on “Little By Little,” the feeling is distinctly Radiohead – repetitive guitar-and-drum soundscapes – but perhaps too derivative. In recent years, there are two clear-cut conversations circling around the topic of Radiohead: The music, and everything else. Last time around, on 2007’s “In Rainbows,” the music was just as interesting as all of the hoopla surrounding the album’s impromptu, pay-what-you-will release. “The King of Limbs” cannot boast the same.
