Kool AD, formerly of rap group Das Racist, recently returned to his native Bay Area and today he released two dual mixtapes dedicated to Bay bus lines. 63 & 19 are follow-ups to his much-underrated 51 mixtape of 2012. They are the second and third in a quartet of solo mixtapes. You can stream and download both 63 and 19 below. I also definitely recommend his recent interview with Fader about the mixtapes’ origins, Oakland, the end of Das Racist, selling drawings on Instagram and growing up.
