999 was first conceived in late 1976. Interest in the band was immediate and constant gigging around London brought with it critical acclaim and a hard core following of supporters. They garnered frequent rotation on radio stations like KROQ in Los Angeles.

And while no one knows how many American bands were first inspired to take up arms by 999, those that did still wear their loyalties loudly."
