This is a list of out-of-the-box, unorthodox albums (metal and non-metal alike) that I've enjoyed for their originality, bravado and sheer retardedness. It's a meagre compilation as of now, but I'll expand it when I hear more of such albums. No order, and subject to change.
P.S.: Feel free to let me know if you know what I don't know...no? O.o
