Hernán Cattáneo (Spanish pronunciation: [eɾˈnaŋ kaˈtane.o]) is an Argentinian house DJ.
Cattáneo began his professional career playing in the early 1990s for the FM Z95, a local radio station largely responsible for the diffusion of electronic dance music in Argentina.
In 1996, he won the residency at Clubland Pacha in Buenos Aires.
As a DJ with an ever increasing fanbase, he rose to No. 22 and then to No. 6 on the DJ Mag poll of the Top 100 DJs.
In May 2007 he released Sequential Volume 2, which was once again followed by another worldwide tour to promote the compilation.
