Comedian/producer Abbey Londer started the Riot LA comedy fest in 2012, seeking to bring Los Angeles a world-class comedy fest to a city that had surprisingly never had one of its own. In four short years, its excellent word-of-mouth has turned it into a phenomenon that this year plays host to the legendary Mel Brooks as he does a Q&A with a screening of "Blazing Saddles" at the Microsoft Theater, and has six sold-out shows by comedian Ali Wong at the Theatre at the Ace Hotel. Londer took some time to discuss the fest and its impressive history with "Kozversations."
