Timeless: The Composer/Arranger Series is the name of a concert series that was created in homage to the composer/arrangers who have influenced hip-hop in the most literal and profound ways. Timeless was conceived by production house Mochilla in Los Angeles during February and March 2009 and included the performances of over 150 musicians in front of ecstatic sold out crowds. These three historic events were recorded and filmed in exacting detail with Mochilla's unmistakable style.
