The producer collaborated with the 'Rehab' singer on her hugely successful 'Back to Black' album and Mark says he will never forget the tragic musician - who died earlier this year at the age of 27 - or her influence on his career.
He said: "I'd been producing records for 12 years before I met Amy and I'd been trying so hard to have hits, but without any luck. The moment I thought to myself: 'I'm never going to make it. I may as well just make music that I like' is the moment I met Amy - we just created what we wanted rather than being concerned with what was on the radio at the time.
"Something like Amy's record comes along once in a lifetime, if that. Ultimately, Amy was one of those rare artists who made a very important record and they loved her. I was just lucky enough to have gone along for the ride."
Mark won his first Grammy award for producing 'Back to Black' but says it didn't change him in any way.
He explained to The Observer magazine: "Winning and having success hasn't changed my life but it has taught me a lot about myself and the nature of this business. The main thing being, to only work on stuff I believe in, regardless of what anyone else thinks."
