Cover art for [The Wall Concept] lyrics by Pink Floyd

"And then he thought it would be cool to build a wall between him and the "fans" so that they could only hear the music, and be forced to love the music for what it is."

Hmm, that's not a bad consept per se, but not what Pink Floyd and Roger Waters inteneded. After the famous incident during a concert when Waters spat on a fan (who I think got up on the stage during a song), he felt that he had buildt a wall between himself and the audience. There's more to it, but that's the very rough meaning.
