Spencer Proffer is one of those behind-the-glass power players who didn’t need a mic stand to leave fingerprints everywhere. After launching Pasha Records in 1978, he locked into his most famous run with Quiet Riot from 1983 to 1986, producing Metal Health, Condition Critical, and QR III—that whole era where the drums got huge, the hooks got sharper, and the mix sounded like chrome. He also worked with Canada’s Kick Axe on Vices (1984) and co-produced King Kobra on Ready to Strike (recorded 1984, released 1985). In my head, “Proffer-era” equals tight, glossy, arena-ready impact—built to slam on vinyl and still sparkle on FM.
