Threat Signal arose from the filthy, industrialized east end of Hamilton, ON Canada, in late 2003. Threat Signal was formed in the late summer of 2003 by cousins Jon and Rich Howard, who then added the guitarist Kyle McKnight. The trio then found drummer Adam Matthews in early 2004. A detuned, syncopated, melodic metal machine, Threat Signal combines the complexity of Bay Area and European thrash, with a more contemporary groove metal sound involving technical rhythms, and musical passages.
