Gravitas was performed live at the Great Pyramid of Cholula on March 16, 2007 near Puebla, Mexico as part of the 21st Mexican National Congress of Astronomy.
Read John Farah's description of this very wonderful and nearly disastrous experience! The GRAVITAS videos were initially going to be projected onto two large screens bracketing the stage where John Farah was performing. Unfortunately, the wind picked up just as the concert was getting underway and blew them down! The concert was stopped briefly and the projectors were pointed at an ancient stone stellae that fronted a human sacrificial altar. This new projection screen turned the concert into something much more intriguing.
