Hi, I made this map (not the Nassau Coliseum stadium). I recreated the stage of the show from February 24-28, 1980, where one of the days was recorded the entire show on the 27th (a restoration is available on the Notelu channel on Youtube, I recommend you check it out.)
This show was a tour of the album released in 1979: Pink Floyd - The Wall, held in 4 cities in 3 different countries: Los Angeles, CA, USA; Uniondale, NY, USA; London, UK/GB and Dortmund, West Germany (1980-81). I based it on several images of the stage on the internet, trying to do it with an eye for detail. The Nassau Coliseum map was made by the TheCraftCrusader channel on Youtube, I give credit to him for who made the stadium.
