In the 1990s, Russell Simmons was instrumental in launching the careers of many of today’s comedy stars through the HBO series Russell Simmons’ Def Comedy Jam. Now, he makes a return to the network with All Def Comedy, which was recorded live on September 7 at the Avalon Theatre in Los Angeles. The event is hosted by Tony Rock and features DJ Drama. This uncensored special showcases a range of stand-up performances from emerging comedians who were discovered at ADD’s weekly comedy showcase, including Chris Powell, Zainab Johnson, Kevin Tate, and Robert Powell, along with Tony Roberts, a seasoned performer from HBO’s Def Comedy Jam.
