I agree with Turpentine -- I think you will find it's harder to create a piece like this than you may believe :nod: There is plenty of material in this piece that could not possibly be said to be simply mindless random note-throwing :musicwhistle: (The "Tango" section, for instance.)
True, a lot of it is dissonant, but that's clearly the intention. Sometimes things have to get ugly in music -- the trick is to make the ugliness compelling in some way, shape, or form (because if it's not, then it is just bull crap. Some would probably argue with me on that statement, saying that even that sort of ugliness is ok, but I would disagree). Music can be story-telling -- and the story isn't always happy or beautiful or even pleasant. I personally found the dark, atmospheric story being told here very fascinating!
Don't get me wrong, though -- if you just plain don't like the piece, then that's your opinion, and it's fine to have that opinion. But before you decide to set that opinion in stone, perhaps think it over some?
