While prepping his just-released Coke Zoo mixtape with Fetty Wap, French Montana has been putting in late nights and long hours on Mac & Cheese: The Album, his long-delayed follow-up to 2013's Excuse My French. Chris Brown (star of the new "Moses" video), Puff Daddy, Wale, and other friends and collaborators have dropped by the sessions to visit the nocturnal rapper. While in the final stretch of recording, Montana let Rolling Stone trail him for a "day." From 7 p.m. to around noon the next day, the rapper put in 17 hours at the studio before retreating to a Hollywood Hills residence for some much-needed rest. Until the album drops, our gallery is the closest you're going to get to the MC's surreal world.
