As soon as Kendrick Lamar dropped "i," people were rushing to their iTunes and bins of vinyl to get a hold of "That Lady," the iconic Isley Brothers tune that was sampled on the rapper's latest single. While some go the all-business route when it comes to repurposing a track, Kendrick made a house call to one of the Motown musicmakers in order to make it happen.

Last night on BBC Radio 1, Kendrick opened up about meeting Ronald Isley and revisiting those famous riffs together in the studio.

"I actually had to go to St. Louis and get the blessings from Ronald Isley," he told Radio 1's Zane Lowe. "That was a trip. We got in the studio and just vibed and talked about how things were back then and how they are now, and you can actually hear him on the record with a few ad libs that he actually did. We got it on camera and things like that, it’s a beautiful thing."

Hold on: camera? Is Kendrick documenting the process behind the next record? We can't wait to see the footage if so.

As for the follow-up to good kid, m.A.A.d city, Kendrick—who's referring to singles as "statements" from now on, according to the same interview—is sizing up the end of his year for the drop of the album. 

"I'm hoping to get it out before the end of the year," he revealed. "I have a lot of great pieces where if my hand was forced to put it out tomorrow, I'd be comfortable with it. But, me being a perfectionist at heart, I really like to sit in with records and not only make it 100 percent, but 110 percent."
