Yasiin Bey (Mos Def) and Ferrari Sheppard — the duo known as Dec. 99th — performed the tracks “Seaside Panic Room” and “N.A.W.” on The Tonight Show Starring Jimmy Fallon on Thursday (December 22). Both songs hail from the duo’s new self-titled debut project, which dropped earlier this week exclusively on TIDAL. While it’s nothing close to what Mos has done in the past, it’s still interesting to see where his artistry has taken him. Watch it above.
