Aftermath was an American power/speed/thrash metal band formed in Tucson, Arizona in 1981, not to be confused with the Chicago-based progressive/technical thrash band (see: Aftermath). In 1986 they temporarily relocated to New York, changing their name to Grudge (see: Grudge (US)) and releasing a studio album on Grudge Records. In 1987 they would return to Arizona under the Aftermath banner, releasing one studio full length before splitting up at some point in the 90s.
