It’s now been over a week since Kanye West unleashed his massive 10th studio album, Donda

And while little is known about what took place in Mercedes-Benz Stadium in Atlanta, outside of those enormous listening parties, legendary producer Mike Dean has opened up to Zane Lowe on Apple Music 1 about what it was like to be part of it. 

“It was interesting,” Dean shares. “It was grueling, lots of hours, lots of changes. Yeah. Came out great though. For this album, it was… I mean, Kanye had three listening parties. So each listening party was like a test kind of. And after each one, I think he wanted… I can’t talk too much about his process. He took all the information he got from everyone, including online reviews, personal friends’ reviews, and [he’d] just kind of digest it all and adjust the album the way he wants.”

Dean continued, revealing where he was during the listening events for the 27-song effort, which just placed 23 tracks on the Billboard Hot 100 today
