Acid Trip? lol jk.
Well if it's more focused on the "rat band" and not the kids or whatever what about "Rat and Roll?" (terrible name is terrible). It's a really... original idea.
though i don't really know what to call it as well, how about make a name for the rat band, and make them the tittle of it..
"afterschool tea time" would be nice, hey wait that's already taken,
how about "true melody" urrgghh too fancy,
i do like rat scat
