Dead - Deal - Gazah Sound and Light Theater, Egypt - 1978....

So I read something,,,,cuz it was in the 80's....probably in Rolling Stone, that the Dead set-up and played inside one of the Pyramids. All went well until Phil Lesh hit a resonant base frequency that was unsettling.

Anyone else remember reading this?
