Although he had been playing for years, it wasn't until the 1990s that R.L. Burnside's raw electrified Delta blues were heard by a wide audience. His new fans celebrated his wild, unbridled energy, so it made sense for him to team with the Jon Spencer Blues Explosion, the warped indie rock band that's all about energy. However, the very purists who celebrate Burnside hate Spencer, believing that the latter mocks the lues. As the blistering Ass Pocket of Whiskey proves, Spencer may not treat the lues with reverence, but he and his band capture the wild essence of juke-joint lues. And that makes them the perfect match for Burnside, who knows his history but isn't burdened by it. Together, Burnside and the Blues Explosion make raw, scintillating, unvarnished lues that positively burns.
