Hernán became a DJ after being inspired by a collection of Chicago house records brought back from America by a friend, featuring artists such as Frankie Knuckles and Inner City. This music played a role in the music he now plays. Hernan describes the music he plays as deep, progressive, funky and tribal house. In 1996, he won the residency at Clubland Pacha in Buenos Aires. His performances were a great success and led to Cattaneo being invited to DJ at clubs around Latin America.
