It's cool to see a band actually go through with something like this. I'm hard-pressed to believe that the arrangements came before the pun, so, assuming this, it's funny to see how committed people can be to it enough to actually arrange a medley like this one. Regardless of the origin of this arrangement, Hard 'n Phirm did a great job of translating Radiohead's experimental, genre-blending sound into a good ol' bluegrass medley. Hopefully we'll see more arrangement ideas like this one covering the works of other bands.
Are there any bluegrass versions of your favorite songs?
