We are still waiting for the closing show soundtrack listing, but
La Presse, which used to cover the fireworks competition on a regular basis during the 1980s and 1990s, just published a rare article about it. It is written by music journalist Alain de Repentigny:

This show will feature a "surround system," which is reported as a first in the event history. Last Saturday night, we could see three steel towers next to the grandstands. Additional speakers shall be located on them.
