Avicii

To put it lightly, what Avicii and his manager Ash have managed to achieve in just a few years is truly astonishing. Commencing his dizzying journey at the tender age of 18, the self-taught, fresh-faced Swedish luminary has unquestionably amassed greater success by the age of 22 than most could ever hope to achieve in a lifetime. The mastermind behind chart-topping phenomena Seek Bromance, My Feelings For You, Fade into Darkness and the current global obsession that is Levels, he has soared from budding bedroom music-maker to international electronic sensation in a matter of years.
