Bluesy, ballsy, and 100% rock 'n roll. Brothers by The Black Keys ($8) is the sixth album from the Akron, OH-based duo, who've been seemingly everywhere over the last decade thanks to song appearances in everything from movies and HBO series to solo albums, side gigs, and collaborations. Brothers isn't a break from their massively minimalistic past, but instead further distills the group's sound down its basic elements of rock, R&B, and blues, with headbangin' results.
