I decided to help someone find a cartoon pilot, so I decided to post their description of the cartoon here
Description: The series was about two boys who are chosen as defenders of rock and fight against villains and monsters with their guitars. The premise of the pilot was that one of them falls in love with a waitress at a pizza place and wants to start playing ballads (very much in the style of Guns N' Roses), but the other refuses until a villain appears with a monster, and they can only defeat it with a ballad.
Can anybody identify this? Also yes this post is in the Lost Media section too, but I put it there incorrectly. Reply to this thread only.
