If someone told us The Black Keys' debut was recorded 40 years ago with a cheap tape machine on a hot night in a backwoods juke joint, we'd probably believe it. Delta bluesman Junior Kimbrough's "Do the Rump" conjures a hypnotic groove with just one pounding snare, a wailing slide guitar, and Dan Auerbach's lustful and slightly distorted voice. Their "She Said She Said" amplifies the angst of The Beatles' original, with double the fuzztone and a drum part even more powerful than Ringo’s.
