Much has been written about the many varied influences and references to be found in this band's work, which is a credit to the duo's mastery when it comes down to delivering the basic ingredients and offering them up as sufficient unto themselves. And they're good at it- very good at it, with this being one very fine album indeed. If you want to know where the spirit of this particular collection comes from, try listening to the first 3 albums by Free before you listen to this. That should get you primed for the treats on offer here, for while Patrick Carney's drums emulate the rock solid angular funk of Free's Simon Kirke, Dan Auerbach appears to be channelling the vocal stylings of Free's Paul Rodgers (especially obvious on the more restrained tracks such as 'Goodbye Babylon') so effectively that when I first heard this record I thought it was by Paul Rodgers! Not only that, but his guitar work carries more than a few hints of Paul Kossoff, particularly in the riff work and his choice of tones. Once again, check out 'Goodbye Babylon' for what I nominate as the best tribute to Free I've ever heard. Keep carrying this torch guys, it suits you!!
