This Sunday Giant Step‘s annual Martin Luther King Jr. celebration is going down. In past years, the celebration has featured the likes of Alex from Jazzanova, Norman Jay, M.B.E., Nickodemus, Rich Medina and DJ Spinna manning the turntables. As you probably figured out from the flyer, DJ ?uestlove will be holding down the wheels of steel this year (with MC Yameen Allworld on the mic). The Mighty Afro will be be putting together a special DJ set celebrating music and freedom. The festivities will be held at Cielo – advance tickets are just $15.
