Tiësto’s first-ever foray into developing budding new talent has been a smash success: the world’s biggest DJ and critically acclaimed producer has selected the winner of his first-ever remix contest, held this fall in conjunction with Beatport, the industry leader in electronic music downloads. The winning remix of “Knock You Out” featuring vocalist/keyboardist Emily Haines of electro-influenced indie rock band Metric was created by San Francisco-based DJ and remixer Ken Loi.
