Dan Auerbach of The Black Keys and Lana Del Rey.

Earlier this year, Dan Auerbach found himself hanging out with a girl in New York.
There's probably nothing too strange about that - after all, Auerbach is newly single after his highly publicised divorce last year.
The only thing is, this girl was kind of well known. Her name? Lana Del Rey.

The North African guitarist and band headed to Auerbach's Nashville studio to record a series of jams, which, while delivered in the electric-blues tradition of nomadic, desert-dwelling Tuareg musicians, resulted in a hypnotic album that rises above worthy World music. Auerbach treated him like any other client, a sound to be enhanced with multi-tracking not just preserved. "He's not a f***ing desert-dweller that lives in a cave," Auerbach told Mojo, "so I didn't treat him like that".

Auerbach approached New Orleans legend Dr John with the idea to make a record that would push him out of his comfort zone. "It was really apparent to me that Mac still has a whole lot of enthusiasm for what he does," Auerbach told The Telegraph. "I just wanted him to make a record he could be really proud of. I didn't want to recreate anything, just to do something fresh, but informed by those old records of Mac's that I love."
