Dogzilla  Dogzilla were an English electronic music duo. The group has had four major releases since 2003 and is composed of Simon Patterson and Richie Kayvan, both based in London. They are most famous for their single "Without You" which charted in numerous countries, including Finland where it reached the number 11 spot. The song also appeared on many respected compilation albums such as Dave Pearce Dance Anthem Classics and former world #1 DJ Paul Van Dyk picked it as his track of the year. Their eponymously titled debut was featured in the 2004 film, 'The Football Factory'. By day Simon works as A&R for Judge Jules and is also resident at Serious @ The Cross, whilst Richie is currently producing a major new band for V2 records. In 2008 Simon Patterson left the project, essentially leading to their dissolution. He has since become a successful trance artist in his own right.
