Jay-Z is no stranger to collaborations with rock stars. The emcee has already worked with U2’s Bono, Coldplay’s Chris Martin and Lenny Kravitz. Now, Jay can add Jack White to that list.

In a recent interview with GQ, White said the two have recorded something “incredible.”

“I just did a record with Jay-Z,” he noted. “We did a song together a few weeks ago. It was incredible. I played him something that I’ve been kicking around for a while and he immediately came out with words for it. It’s unbelievable-sounding.”

It is still unclear if this song will be featured on Jay-Z’s next project. Last month, Jay spoke on the next album, saying he had at least one “crazy” song completed.

“I got one crazy record. To be honest with you, it’s crazy. I got one and we’ll build from there. Whether it comes out this year or next year, it depends on the music and how it’s coming out. I don’t really have any dates.”
