Golden Smog is a loosely connected group of musicians comprised, at various times, of members of Soul Asylum, The Replacements, Wilco, The Jayhawks, Run Westy Run, The Honeydogs and Big Star. Golden Smog's lineup has often changed, but relative constants who appear on all the recordings are guitarists Kraig Johnson (Run Westy Run), Dan Murphy (Soul Asylum) and Gary Louris (The Jayhawks), along with bassist Marc Perlman (The Jayhawks).

The group took their name from a nickname given to Fred Flintstone, which, in turn, was a parody of singer Mel Tormé's nickname (The Velvet Fog).
