For a duo, The Black Keys make an impressively expansive sound, and a lot of that boils down to the inspirations that fed into their music. While Patrick Carney grew up on punk groups like The Clash and the Cramps, Dan Auerbach came up on bluesmen like Junior Kimbrough and southern rockers like Lynyrd Skynyrd. Throw in Steppenwolf, T. Rex, and Captain Beefheart, and you'll see why they didn't stay in the garage for long.
