"Ecto Plasmic Assault were based in Vancouver in the late 60’s and did many shows at Roger Schiffer’s Retinal Circus.
Bob Montgomery from Florida started Ecto Plasmic Assault along with Max Andersen and did some shows as Ecto Plasmic Assault before renaming the Light Show to GoddaMatch.
Five people were involved using 3 film projectors, 22 slide projectors, 5 overheads, and some motorized effects.
The equipment from Ecto Plasmic Assault/GoddaMatch was later passed onto Greg Evans from Acid Rain Light Show". From the website www.pooterland.comLive Sound & Lights
For physical events that happen at a specific time. For example a concert, or dance performance. If there are multiple shows, you can still duplicate your event to cover them all.
