Jos Kloek is the Belgian producer/sound engineer who put a hard edge on a whole slice of 80s European heavy metal. I keep seeing his name in the credits: producing Killer (1983-84, "Shock Waves"), Axe Victims, Fisc, Dark Wizard and Warhead (1984), and even signing as Jos "Speed Rat" Kloek on Warhead's "The Day After" (1986). He guided Crossfire through 1984-86 (remix work, then production), and in 1985 took the desk for E.F. Band while mixing Together's "Playing Games" EP. His peak run is 1985-87: producing/engineering TSA and then mixing, producing and engineering Kat's debut "Metal and Hell" (1986) and related releases into 1987. Later credits include Van Camp (1988), FN Guns (1990) and Asphyxia (1991, executive producer).
