MF DOOM‘s career spanned over two decades, but there are still people who don’t know about the late lyricist’s resume – and Playboi Carti is here to school them.

In an interview with Inked Magazine published on Tuesday (March 9), Carti detailed the recording session for his Whole Lotta Red cut “Stop Breathing” where he raps, “I just hit a lick with a mask, MF DOOM!” The engineer – who also happens to be his best friend – had no idea who the late underground legend was, so a history lesson was in order.

“I had to tell my boy, my best friend, my engineer,” Carti recalled. “He’s the person recording the song, and he didn’t know who MF DOOM was. I’m like, ‘You don’t know MF DOOM? You don’t know who this dude is?’ I had to play songs for him, because he didn’t know who he inspired. The mask! I’m anonymous myself, but he’s king of that.

“I don’t have to sound like MF DOOM to be inspired by him,” he continued. “Nobody can keep a leash on him. Nobody can keep a leash on me. That’s definitely his impact. Even if I didn’t know that at first, I had to look up and think about this shit right here—it had already been done.”

The Whole Lotta Red shout out came just days before DOOM’s wife Jasmine announced his unexpected passing on December 31 – but she revealed his death had actually happened two months prior in October. He was 49.
