This video is by no means new, but it's still absolutely entertaining and informative. DJ Stretch Armstrong and Bobbito Garcia sit down with Chairman Jefferson Mao for a Red Bull Music Academy lecture, discussing the beauty of college radio and their role in launching careers of artists like Jay Z, Nas, and Mobb Deep. For those unfamiliar with Stretch and Bobbito, the two co-hosted The Stretch Armstrong and Bobbito Show on 89.9 WKCR in New York during the majority of the 1990s. In 1998, The Source named the show the "Best Hip-Hop Radio Show of All Time." Suffice it to say, these two have an important place in hip-hop culture, and have a wealth of knowledge to offer. Sit back and watch the video below.
