If you think this tune sounds familiar (or the name does), then you might be thinking of Queens of the Stone Age’s In My Head of which this is the original version. Desert Sessions is pretty much just that: Josh Homme takes a group of musicians to a ranch out in the desert and they jam and record music. Some of their output has gone on to be re-recorded by Queens of Stone Age, including this one.
This version isn’t quite as heavy as the Queens of the Stone Age version, but it does feature a running piano (at least, I think it’s a piano) motif that didn’t make it into their version. For shame! It’s quite lovely, and matches the more relaxed nature of this version.
