Even one of the most prolific producers in the game struggled to keep pace with Guwop.

Gucci Mane is the hardest working man in hip-hop.

Prior to his prison sentence — and even while he was locked up — the 1017 Brick Squad boss became legendary for his insanely prolific output (and this was before he got clean). Since his release from jail last May, Guwop has only tightened his grip on that title, dropping a total of eight projects in addition to countless videos, loosies and guest verses.

Gucci’s work ethic is so tireless that even Metro Boomin, his Droptopwop collaborator and one of the busiest producers of the last few years, struggled to keep pace.

In a new interview with Beats 1’s Zane Lowe, Gucci reveals how the pair created those 12 DropTopWop songs over just a two day period (which is a pretty incredible feat in itself), but it would have been more if Metro hadn’t have succumbed to the natural human recovery process known as sleep — something you have to genuinely question whether Gucci does.

“Metro used to always come by my studio when he was still going to school, when he was 18/19-years-old. A lot of times he’d come to the studio and I’d kick it with him, but I’d never rap on his beats. And he’d be like, ‘Gucci, why you never rap on my beats?’ To see what he’s doing now, every time he pull something up it make me wanna rap, it make me wanna record. We did 12 songs in two days; the only reason we didn’t do more songs is because Metro fell asleep!”

Metro Boomin isn’t the only collaborator who’s witnessed Gucci Mane’s superhuman work ethic in person; in The FADER’s oral history from 2015, Mike WiLL Made-It remembers watching Guwop rap on 20 beats in three days (“all freestyles”) while DJ Holiday says sleep is indeed the cousin of death in Gucci’s eyes: “He was always like, ‘They sleep, bruh. They sleepin; I’m working. That’s how we gonna kill ’em.’ And that’s what we did.”
