ISW came to fruition at the Transmission Theater, a now-defunct venue (a former Transmission Shop), located at 314 11th St., in San Francisco’s South of Market District in 1995. It originated at an event at the DNA Lounge in 1990, "The Sleazefest", put together by future Hayride to Hell drummer Joey Myers, Wrestling/Music/Movie entrepreneur Johnny Legend, and local music/events promoter August Ragone. This show featured live music performances by The Mummies, The Phantom Surfers, and Johnny Legend and His Rockabilly Bastards, video presentations, and a Lucha Libre match between Ragone and future Hellbillys frontman, Barrie Evans. The Lucha Libre aspects were built upon with each subsequent Johnny Legend show at various venues around the Bay Area, until the early part of 1995, when they were tapped to do their first all-wrestling event.
