On his latest album, Grass, singer-songwriter Keller Williams applies his twisted spin to yet another genre project. This time, he gives bluegrass arrangements to a set of original and surprisingly adaptable cover songs. It's no revelation that the pair of Grateful Dead covers "Loser" and "Dupree's Diamond Blues" adjust quite well to Williams' banjos and mandolins. But the real treat is the acoustic take on "Another Brick in the Wall," which turns Pink Floyd's British-school rant into a backwoods call for hillbilly autonomy. Williams, a one-man band in concert, packs his shows with bizarre covers.
