LORELAI: You are not sleeping through this.
RORY: Through what?
(Lorelai walks over to the bed and leans over her.)
LORELAI: The freaking Blue Man Group is outside our house!
The Blue Man Group is a performance art company founded in Manhattan in 1987 by Chris Wink, Matt Goldman and Phil Stanton. What began as a series of “street disturbances” by a group of men wearing blue masks became a series of shows combining music and art held in small clubs, and eventually a full performance at the Astor Theatre in New York in 1991, which is still on-going.
The Blue Man Group have gone on a number of concert tours, and released several albums. At the time this episode went to air, The Blue Man Group were booked to play live in Las Vegas, which continued until 2005. The Blue Man Group eventually went international, and in 2017 were bought by Cirque Du Soleil.
Interestingly, Nathan Wetherington, who played Dean Forester in the original Pilot episode, was the drummer with the Blue Man Group for two years.
