Yeah, it would be pretty sweet to hear Radiohead perform all of OK Computer live. But since that is almost certainly not going to happen, a group of Bay Area music obsessives has come up with quite possibly the next best thing. First, the folks behind Undercover Presents pick a classic album — maybe something recent, like OK Computer, or something older, like Sly and the Family Stone's 1969 tour de force Stand! Then they find a bunch of Bay Area musicians, usually bands or ensembles of varying genre inclinations, to cover one song each from the album. The groups privately rehearse and record their song, free to take a great deal of liberty in their interpretation. Then they perform the whole album live in sequence, usually over a couple of nights, often to a sold-out crowd. If this sounds like a major undertaking, it is: UnderCover usually puts on only one or two shows a year. The results, though, can be stunning — a sometimes-revelatory, always novel take on songs you've probably heard a million times. And as great as Radiohead is, the band ain't gonna do that.
