Calvin Harris started off making quirky disco-fied pop records like ‘Acceptable In The ’80s’ and ‘Girls’ before he got his big room EDM producer head on. ‘I’m Not Alone’ was his first UK chart-topper and after he decided to work with guest vocalists instead of singing himself on his own tracks, the whole of his third album, ’18 Months’ — featuring the likes of Kelis, Rihanna, Ne-Yo, Florence Welch, Tinie Tempah, Ellie Goulding and Ayah Marar — spawned a massive nine UK top ten singles.
