The Black Keys frontman Dan Auberbach has spoken out about his work producing Lana Del Rey's new album, Ultraviolence - claiming that the pair often fought and 'bumped heads'.
The follow-up to the smash breakthrough Born To Die will be released later this year, following the release of the Auerbach-produced single 'West Coast' last month.
Now, speaking to Mojo about the making of Ultraviolence, Auerbach said that it wasn't always smooth sailing.
"We were only scheduled to do three days, and then she stretched it out to two weeks and we finished a whole record. She's the real deal," he said.
"She impressed me every day. There were moments when she was fighting me. I could sense that maybe she didn't want to have anybody think she wasn't in control because I'm sure it's really hard to be a woman in the music business. So we bumped heads a little bit, but at the end of the day we were dancing to the songs."
