Has anyone ever seen the movie YellowBrickRoad? And no, it's completely different than Wizard Of Oz.

It's like, this crazy psychological movie about these people who are trying to make a book about this whole civilization that left their city to go north through an unmarked trail. So they decide to go through the trail, which they call "The Yellow Brick Road", and they all start hearing this really loud big band música that never stops! They also find a hat from the 1930's, but is still completely intact. Alot más stuff happens, but I don't wanna ruin it for you. It's really good.
But seriously, has anyone else seen it?
