After serving as house lighting engineer for several Grateful Dead shows, including their 1971 residency at the
Capitol Theatre, Port Chester, she was recruited by the band's
Jerry Garcia to work for them full-time.[1] She started working regularly for the Dead on their 1972 tour of Europe (which was recorded and released as Europe 72), and remained their in-house lighting engineer for the remainder of their career.[1] One particular challenge that Brightman faced was having to alter lighting setups immediately in response to the Dead's improvisational style. By the band's final tours in the mid-1990s, she was operating a computer-controlled lighting system and managing a team of technicians.[5] Her work inspired
Phish's resident lighting engineer
Chris Kuroda, who regularly studied techniques in order to keep up with her standards.[6]
Brightman continued working in related spin-off projects until 2005.[1][7] She returned to direct the lighting for the
Fare Thee Well concerts in 2015, where she used over 500 fixtures.[8]
In 2020, the Capitol Theatre blog listed Brightman as being one of the most influential women in the Grateful Dead's history.[9]
