Ronson started DJing when he was 17. "I got really into hip hop," he told CBS News' Anthony Mason. "I knew I was never gonna be a rapper, and I didn't know anything about producing. So I thought, 'Okay, DJing, that's my way into this thing that I love.' I started to collect vinyl and then I started to listen to all the great New York radio DJs, like Funk Master Flex and Stretch Armstrong and taught myself the routines.
He got his first gig by being "pushy," he said. "But it was in a snowstorm in the middle of New York. I had to bring all my own equipment to some weird bar that served underage kids. I had a lot of my dad's old soul records, like Average White Band and things like that, mixed with the hip hop of the time.
"I just loved playing music for people, and something about getting people on the dance floor but also playing music they weren't used to hearing instantly appealed to me."
