For the past year or so, the great rap producer Kenny Beats has been inviting rappers into his studio for a YouTube series called The Cave. The premise is simple: The rapper tells Kenny what kind of beat they want, he quickly throws together an instrumental for them, and they freestyle over it on-camera. He’s had people like Vince Staples, Denzel Curry, Rico Nasty, and Danny Brown on the show. And now he’s had Thundercat.

Thundercat, as you probably know, is not really a rapper. But although his episode of The Cave mostly involves drinking a lot of Yerba mate and goofing around in the studio — he also brings his bass guitar along for the ride — he does, in fact, end up delivering a short non-sequitur-laden freestyle that concludes with the line “I miss my cat.” Bars, man.
