William Rosario produces IDM/Ambient Electronic Music as Asymmetrical Head and Minimal/Ambient/Tech House as QUILIUQ.

Will has a wide range of musical influences from Hip Hop, New Wave, Industrial, House, and Techno that is quite apparently showcased with both of his alias'. Always interested in being involved with the music in any form, he started djing in the mid 90s at house parties and art galleries mixing the obscure with the familiar. He started making music in 2002 when he collaborated with an old friend making shoegazy electronic music. They both went their separate ways and he began to produce IDM/Ambent as Asymmetrical Head in 2002.

In the past seven years, he has released 2 albums (Oblique Formation in 2004 and Feeling Sorry For Inanimate Objects in 2008) with a handful of EPs, Remixes, and Compilations.

He has revisited his Techno House roots in the past couple of years and has started on production for QUILIUQ's first album which is set for release in 2012.

Besides making Electronic music, Will also co-runs a new label out of Los Angeles, CA called Architects + Heroes Records with Stephen Ruiz and H.A. Eugene. He also runs a freelance Graphic and Web Design firm called Leftm Graphics.
