The son of a Jamaican DJ, Flex was born in The Bronx as Aston Taylor, Jr and bought his first set of turntables at age 16. He was influenced by early New York Hip-Hop DJs such as DJ Red Alert. His radio career began at KISS-FM as an assistant to Chuck Chillout in the late 1980s. When Chillout transferred to WBLS, Flex accompanied him and soon began spinning at clubs and parties, where people began to take note of his skills. Among those fascinated with his talents were the programming chiefs at Hot 97.1 FM, who offered him a prominent role as one of the city's top hip-hop DJs. In 1995, he released his first major-label mix album, The Mix Tape, Vol. 1: 60 Minutes of Funk, and followed this album with two more volumes on Loud Records by the end of the 1990s, along with an album on Def Jam, The Tunnel. In 2000, he mixed a collection of that year's biggest rap anthems for Arista, Vibe Hits, Vol. 1, and continued the 60 Minutes of Funk series. In addition to his duties as a radio DJ and as a successful album artist, Funk Flex has also served as a remixer and host of the Spike TV series Ride with Funkmaster Flex. The 2005 album Funkmaster Flex Car Show Tour featured music from the successful series. He also had a show on ESPN called All Muscle with Funkmaster Flex. As a huge street car fanatic, he founded and started his own custom car club "Team Baurtwell."
