Yasiin Bey (Mos Def) has released a new song under his former moniker – Mos Def. The song “Sensei on the Block” is the first new piece of music he’s released as Mos Def in a very long time. Mos Def has put out a few tracks as Yasiin Bey and has appeared on other artists’ tracks, but he hasn’t released an album since 2009s “The Ecstatic.” He teamed up with Ski Beatz for the track that shows it’s not clear whether this is part of a larger project, but new music from him is always a good thing. You can find the song on iTunes, Spotify, and other major digital music platforms.
