In almost every musical genre you will find artists that are labled "underground". Characterized by unorthodox styles that defy categorization, a willingness to push musical boudaries, and a fiercely loyal and sometimes cult-like fanbase, they often create works that actually define the genre. In this special episode of The Bridge, Ralph digs deep into the crates to showcase videos from hip hop's underground pioneers. Join Ralph as he hangs out at Opus 22, NYC's hottest turntable lounge, and presents videos from artists such as KMD, Main Source, Organized Konfusion, Diamond D and Black Moon.
