= Live Event Visual Amplification =
Event Visual Amplification is the display of live and pre-recorded images as a part of a live stage event.
Visual amplification began when films, projected onto a stage, added characters or background information to a production.
35 mm motion picture projectors became available in 1910 - but which theatre or opera company first used a movie in a stage production is not known.
In 1935 less costly 16 mm film equipment allowed many other performance groups and school theaters to use motion pictures in productions.
In 1970 closed circuit Video cameras and recorders became available and Live Event Visual Amplification came of age.

Introduction
Live Event Visual Amplification is the display of live and pre-recorded images as a part of a live stage event.
Visual amplification began when films, projected onto a stage, added characters or background information to a production.
35 mm motion picture projectors became available in 1910 - but which theatre or opera company first used a movie in a stage production is not known.
In 1935 less costly 16 mm film equipment allowed many other performance groups and school theaters to use motion pictures in productions.
In 1970 closed circuit Video cameras and recorders became available and Live Event Visual Amplification came of age. For the first time live closeups of stage performers could be displayed in real time. These systems also made it possible to show pre-recorded videos that added information & visual intensity to a live event.
One of the first video touring systems was created by TJ McHose in 1975 for the Rock and Roll band The Tubes using black and white TV monitors.
In 1978 TJ McHose designed a touring color video system that enlarged performers at the Kool Jazz Festivals in sports stadiums across the USA.

=Live Event Visual Reinforcement=
Introduction
Live Event Visual Reinforcement is the addition of projected light effects and images onto any type of performance venue.
Visual Reinforcement began more than 2000 years ago In China during the Han Dynasty Shadow puppetry was invented to "bring back to life" Emperor Wu's favorite concubine. Mongolian troops spread Shadow play throughout Asia and the Middle East in the 13th century. Shadow puppetry reached Taiwan in 1650, and missionaries brought it to France in 1767.
The next major advance in Visual reinforcement for events was the Magic lantern, first conceptualized by Giovanni Battista della Porta in his 1558 work Magiae naturalis. The Magic Lantern became practical by 1750 with the oil lamp and glass lenses. Special effect animation attachments were added in the 1830ies. In 1854 the Ambrotype positive photographic process on glass made Magic lantern slide creation much less expensive.
Magic lanterns were greatly improved by the application of Limelight to live stage production in 1837 at Covent Garden Theatre and improved again when electric arc lighting became available in 1880.
In 1910 Adolf Linnebach invented the Linnebach lantern a lensless wide angle glass slide projector.
In 1933 the Gobo metal shadow pattern for the ellipsoidal spotlight allowed images to appear and disappear by dimmer control.
In 1935 16 mm Kodachrome film projectors added the first fully animated Visual reinforcement to Live Events.

- Roy Seburn (one of Ken Kesey's Pranksters) who introduced this new artform to the younger bohemians through the Acid Tests. He had probably attended one of the Beat Generation lightshows (I don't think they called them lightshows at that point, maybe liquid art shows), thought it was a groove and figured out how to duplicate it. This type of lighting technique is known as liquid projection. A clear container (usually a glass clock face crystal) is placed on the overhead projector and a liquid consisting of water and colored oil is placed in the container. The container is rocked in time to whatever music happens to be playing.
= Live Event Sound Reinforcement =
Introduction
A sound reinforcement system was first developed for movie theatres in 1927 when "The Jazz Singer" was released. Movie theatre sound was greatly improved in 1937 when the Shearer Horn system debuted. One of the first large scale outdoor public address systems was at 1939 New York World's Fair
In the 1960ies Rock and Roll concerts promoted by Bill Graham at The Fillmore created a need for quickly changeable sound systems. In the early 1970ies Graham founded FM Productions to provide touring sound & light systems. By 1976 in San Francisco the technical debate over infinite baffle vs horn-loaded enclosures, and line arrays vs distributed driver arrays, was ongoing at FM because of the proximity of The Grateful Dead and their scene Ultrasound, John Meyer, and others). But at that time there were parallel developments in other parts of the USA - Showco (Dallas) and Clair Bros (Philly) had different approaches, Clair in particular was moving in the direction of modular full-range enclosures. They'd rig as many as needed (or clients like Bruce Springsteen could afford) in whatever configuration they thought would cover a particular venue. Stanal Sound in southern California) used fiberglass futuristic looking equipment for artists like Kenny Rogers.
There is a significant group of long time Sound professionals who feel that live concert sound quality has not greatly improved since 1978 despite all the digital, wireless, fiber optic, and computer advancements that have made it much easier to tune to a specific venue and assemble and maintain a touring system.

Touring Packaging
Touring systems must: unload from the truck gently, roll easily into their stage location, connect to each other quickly. A well designed system includes duplicates of critical components and "field-replaceable" items such as cables, switches, and fuses. Every component must be protected by a well padded road case that has room for all connector cables and allows easy access to the components for fast cable re-patching to bypass a bad component and for repairs during a tour. The road cases must also be well ventilated and for outdoor use should be white to minimize solar heat buildup. Road case sizes should be modular to pack tightly together on the truck.
