This speed metal band was formed in the USA in 1986, and was built around the nucleus of up-and-coming guitar wizards Marty Friedman and Jason Becker. Recruiting drummer Atma Anur and ex-Le Mans vocalist Peter Marrino, they debuted with Speed Metal Symphony, a predominantly instrumental album that fused classical, blues and hard rock styles. Friedman and Becker then went on to record individual solo albums in a similar vein, before returning to work with the band. Go Off!, released in 1989, marked the arrival of Jimmy OShea and Deen Castronovo on bass and drums, respectively. This album reinforced the bands hi-tech instrumental approach, and featured complex passages where the guitars of Friedman and Becker duelled for supremacy. The album was a commercial failure and Cacophony subsequently folded in 1990, with Becker joining Dave Lee Roth and Friedman joining Megadeth.
