Go back and listen to The King of Limbs, the album Radiohead released online last year. Chances are pretty good you'll find a bunch of things going on in there you didn't hear the first few times you listened before dismissing it with a shrug. In a catalog filled with thorny and often impenetrable albums, the band's eighth is the easiest to give up on when the going gets tough. Not so coincidentally, much of this has to do with the way the album was released: without much notice, online as a discount download, and with very little promotion by the band. In a way, it doesn't seem like much of an album, at least at first. It's also the band's shortest LP. But go back and listen to The King of Limbs. Buried deep in the sounds of a band still playing at its peak is a record of intense warmth and raging inventiveness. The songs are based on loops and samples and traditional instruments filtered through new methods of recording. In a way, it's Radiohead's most intricate work, a rich and, yes, rewarding piece of music that isn't as disposable as it initially appears. The group brings the songs, reworked and stage-sturdy, to Blossom this week, along with some new cuts and old faves. With Caribou. 7:30 p.m. Tickets: $43 and $69.50.– Michael Gallucci
