It's being called the "Magic on Medary".

With a mixture of about 1,200 alumni and students looking on, the concert choir put a resounding exclamation point on the Alumni Green dedication with a performance at the base of the Campanile. Video filled the brick of the 165-foot structure during the 11-minute finale, ending with a 30-foot SDSU logo.
 
Despite a threat of lightning and a tornado warning, the finale featuring Henkin Schultz Creative Services and Dr. Laura Diddle’s concert choir went on as scheduled at 8:30 pm.
