A few weeks ago, Mos Def (Yasiin Bey) unexpectedly shared with fans a new song titled “Dec 99th – N.A.W.,” given that he had announced his retirement from film and music in January of this year.

However, today, Bey teams up with Ferrari Sheppard, co-founder of A Country Called Earth for yet another new track titled “Dec 99th – Tall Sleeves.”

For the track, the production features a glitchy, futuristic beat as Mos Def raps and sings over it. At this point, it is unclear if it will be in any of Yasiin’s upcoming projects.

In the meantime, take a listen to “Dec 99th – Tall Sleeves” below.
