Tinhorn, formed in 2005, is a Los Angeles based heavy metal group formed by guitarist Harrison Thomas and drummer Jonathan Thomas, sons of Canadian comedian Dave Thomas of SCTV fame. Within two years, the lineup was solidified by the joining of Danny Ball and Pascual Romero, bassist of the metalcore band In This Moment. Tinhorn has made appearances on Tom Green Live  and compose music for television shows including G4's Code Monkeys and the internet-based comedy created by comedian Jordan Black entitled The Black Version.
