In January 2016, Kanye West released his Kendrick Lamar collab “No More Parties in L.A.” with production from Madlib. During Red Bull Music Academy Festival New York 2016 this month, the legendary producer sat down with Chairman Mao for an hour-long conversation tracing his early influences and recent collabs. The most interesting tidbit is around the 21-minute mark where Madlib reveals the beat behind “No More Parties in L.A.” was made on an iPad.

The intro to the record samples “Give Me My Love” by Johnny “Guitar” Watson and flips into a heavy loop of Junie Morrison’s “Suzie Thundertussy.” He told RBMA:

“I just wanted to leave it the same, dudes get mad, ‘That dude just looped that shit up…That’s my sound, I’m a loop digger so I just wanted to leave it like that and make it dirtier than it was.”

Madlib also explained that the rest of the beats he gave Kanye were later picked up by his frequent collaborator Freddie Gibbs. “Everytime I sample a record, I sample off the whole record,” he said. “I made beats out of the whole record, but they just picked that beat.” Beats from that session have now made their way onto Bandana, his forthcoming collab project with Freddie Gibbs.

The day of its release, fans traced the making of “No More Parties in L.A.” back to 2010 and the My Beautiful Dark Twisted Fantasy sessions. Then, bonus footage from Stones Throw’s Our Vinyl Weighs a Ton documentary seemed to corroborate those reports with Kanye talking about working with Madlib in the studio.
