Calvin Harris The $100 Million DJ

How did Calvin Harris go from stacking shelves in his local supermarket to such astonishing global success? He's come a long way from making music in his bedroom in his native Dumfries but since bursting onto the music scene with "Acceptable in the 80s" in 2007, he has broken Michael Jackson's record for most hits from one album, become the first British artist to have one billion plays on Spotify and turned hit-maker for stars like Kylie Minogue, Rihanna, Cheryl Cole and Dizzee Rascal. This is the astonishing story of Calvin Harris's journey from struggling musician to international star, revealing what makes him tick, why he has the Midas touch, how he went from being a lanky kid with little self-confidence to a modeling deal with Armani and how he became a global megastar.
