In August, 1967, Joshua White was engaged by rock promoter Bill Graham to recreate the San Francisco "Summer of Love" experience at the O'Keefe Center in Toronto for a series of concerts featuring the Jefferson Airplane and Grateful Dead. The following year Graham opened the Fillmore East and hired the Joshua Light Show under White's direction to provide the lighting and visual environment for all of the theater's headline acts. White left the Fillmore and Joshua Light Show in the spring of 1970. By the summer, he had developed Joshua Television, a large screen color video magnification system for big events. His first client was Bill Graham who was presenting concerts at Tanglewood.

Joshua White has since worked in television as a director/producer. He began working in rock TV with Dick Clark and Don Kirschner in 1972, and produced and directed the network TV series, In Concert. His credits include Seinfeld, Flying Blind, The Original Max Talking Headroom Show, An Evening with Utopia, The Pirates of Penzance, Delta House, National Lampoon's Disco Beaver from Outer Space, the Jerry Lewis Telethon, and Inside the Actors Studio. White also recreated his light show in the movies Midnight Cowboy and The Rose. He received an Emmy nomination in 1973 for his direction of In Concert Cat Stevens: Moon & Star

Documentation of White's original lightshow was included in the Summer of Love: Art of the Psychedelic Era exhibition, which originated at the Tate Liverpool and travelled to Schirn Kunsthalle Frankfurt, Kunsthalle Wien, and the Whitney Museum in New York.

His film "Liquid Loops" was screened as part of the Visual Music exhibition at the Los Angeles Museum of Contemporary Art and the Hirshhorn Museum in Washington D.C., and subsequently released on DVD by the Center for Visual Music.

White's decade-long series of installation work with the artist Mike Smith was recently exhibited as part of Mike's World: Michael Smith & Joshua White (and other collaborators) at the Blanton Museum of Art in Austin, Texas and The Philadelphia Institute of Contemporary Art.

In 2004, he created a lightshow with artist Gary Panter, with whom he continues to collaborate, and he is currently developing a new project with photographer/filmmaker Alyson Denny.

White's first performance since 1969 billed as "Joshua Light Show" was presented in April 2007 at The Kitchen, which he followed up with a headlining appearance at the annual Netmage live media festival in Bologna and a week-long residency at Issue Project Room in Brooklyn.

The Joshua Light Show is a team of multimedia artists led by White, including senior collaborator Bec Stupak, Alyson Denny, Seth Kirby, and Brock Monroe.

Members emeritus include Bill Schwarzbach, Thomas Shoesmith, Cecily Hoyt, Ken Richman, Lois Zelman and Jane Rixmann
