Nike brought together three generations of rap royalty when they recruited DJ Premier, Kanye West, Nas, Rakim and KRS-One for “Classic (Better Than I’ve Ever Been)” to celebrate the 25th anniversary of their beloved Air Force 1 sneaker in 2007.

In the latest episode of his YouTube series So Wassup?, Premo broke down the backstory behind the all-star collaboration. The legendary producer began by revealing Kanye received a beat CD from Rick Rubin and was tasked with choosing the instrumental that he, Nas, Rakim and KRS-One would rap over.

However, after the original version (which didn’t feature Rakim due to his verse being a slower tempo) was completed, Premo received a phone call from KRS asking him to do a remix.

“KRS-One called me and said, ‘Yo, we need a Premier version of this song,'” he remembered. “I had no ties to it, but when KRS calls, what do you say, no? No. You’re like, ‘Alright, what do you need me to do?’ He said, ‘The original is done, we even performed it already on MTV. But we still need one to do a video to and we really want to get it a little more — not even uptempo, just more of a different type of energy.’ I said, ‘Alright.'”
