Battle of the Bands
From Futurepedia, the Back to the Future Wiki
The Battle of the Bands was a competition held in the Hill Valley High School gymnasium to determine the best band in Hill Valley in 1985. Marty McFly and The Pinheads auditioned in front of four judges. One of the judges told the band that they were "too darn loud".
[edit] Behind the scenes
The judge that stops Marty is played by Huey Lewis.
