Call me conventional, but my favorite concept album is Pink Floyds The Wall. The entire album seems to relate to the lives of so many people I know. The song Mother comes into mind immediately my roommate Nick has an overprotective mother; she literally runs every aspect of his life. She has all these fears of the world within herself and she unknowingly projects these fears onto him, her protection is ruining his life (Roger Waters knows his shit uh?). Ive tried to get him to listen to this album for that realization and other things, but he refuses. Anyway, that is just one of the many reasons The Wall is my favorite.
