The bass guitar Brandon plays is the same guitar used in the short film the movie was based on.
The guitarist on the cover of Rock magazine is Erik Signor, the actual guitarist of Voices, the band whose songs are used as La Fenetre.
The opening of the first concert scene is an homage to the beginning of Back to the Future.
The "commercial" playing in the background while Brandon informs Avery of the Lee Page article in Rock magazine, is actually a short film Evan and Anthony filmed many years earlier while on a trip to Boston.
