While America was never in danger of a shortage of Caucasian blues rock bands in the wake of a `90s mini-revival, few Delta-inspired acts harbored as much sorrow and fire within its songs as the Akron, Ohio, duo the Black Keys. Singer/guitarist Dan Auerbach and drummer Patrick Carney hooked up in the mid-1990s and initially gained a cult following as a straight-up gin-soaked blues act. As their notoriety grew, elements of indie and garage crept in. As the pair released one critically doted upon album after another in the `00s, their sound proved eclectic and ever-evolving as the array of labels to which the act was signed (Fat Possum, Epitaph, Alive, etc.).
