Mos Def hasn't put out a solo album since The Ecstatic, one of 2009's best records. Since then, he has changed his name to Yasiin Bey and hasn't done a ton of recording or acting. But last year, he resurfaced, sorta, when a snippet from the track "Twilite Speedball" popped up in an ad for the Cosmopolitan hotel in Las Vegas. if you find the music intoxicating, introduce yourself to the song.
