Before he was a star producer, Fraser T Smith played prog with Rick Wakeman and was the guitarist for pop-soul sensation Craig David. The diverse background served him well as a producer who could do every form of modern pop, from the spiky Kaiser Chiefs to the elegant Ellie Goulding to the diva moves of Britney Spears. Overseeing a track on Adele's 21 is just one feather in Smith's cap.
