There are more than a few parallels between the White Stripes and The Black Keys that go well beyond their simple guitar/drums architecture. The Keys have recently embarked on an even odder array of outside gigs than Jack White, including guitarist Dan Auerbach's production duties and excellent, diverse and nuanced solo album and drummer Patrick Carney's new outfit, appropriately dubbed Drummer. Both have hit the road in support of their new albums in full band configurations. They also entered into a collaboration with rapper Jim Jones called Blackroc. All of this, plus Carney's recent divorce and relocation to Brooklyn, had a direct impact on the direction The Black Keys took on its latest album, 'Brothers.'
