If you are even vaguely in the mood to listen to the former Das Racist rapper Kool A.D. today, you are in luck, because Kool A.D. just released so much free music. The man has two new mixtapes, 63 and 19 (both named after Bay Area bus lines). We recently posted his “Eroika” video, but there’s a whole lot more where that came from — 38 tracks, as it happens. Lakutis, Busdriver, Meyhem Lauren, DaVinci, Spank Rock, Issue, Maffew Ragazino, and a ton of other guys make guest appearances, and Kool A.D. even brings out an old, unused Ad-Rock beat that the former Beastie Boy sent to Das Racist a few years ago. Check out both tapes below.
