Just for a topic to investigate. There must be some examples out there.
Skyrillex? It’s not technically music and it’s ugly (though I don’t hate it and can see how they have hordes of fans).
Eh, what I’ve heard of Skrillex I don’t mind. Of course it’s music.
My choice would be the completely nonmelodic, screamy, Cookie-Monster-vocalized end of the death metal spectrum. Stuff like Lamb of God and Slayer.
I still won’t say it’s not music because obviously there are a lot of people out there who like it. But I will say it’s ugly music.
There’s a genre called “noise music,” although it’s not what most people would call music. Example
Man, that sho is ugly!
Philip Glass.
Yoko Ono.
Feeble attempts, all of you!!! 
For the win, I give you Penderecki’s Threnody for the Victims of Hiroshima: Penderecki: Threnody for the Victims of Hiroshima - YouTube
It was written to evoke the feeling of skin crisping off bodies…and succeeds.
The new Flaming Lips cover album of Sgt. Pepper. Awful.
I don’t think ugly music has to mean bad music, or that bad music is necessarily ugly. Sometimes you want ugly. I would say most heavy metal is ugly, especially Black Sabbath. Much of it is good too, though, and, in certain moods, it can be what I want to listen to.
My usual choice for these kind of threads: German free jazz musician Peter Brotzmann’s 1968 album “Machine Gun”.
Okay, that makes me want to bomb Dresden and Berlin again. :mad:
Apparently they’re a big deal in the metal world, but Gwar’s cover of the Pet shop Boys West End Girls is horrendous. I’d heard it just today (the original) and trending on Facebook was that this band Gwar had done a cover. So I checked it out. I wish I could un-listen and un-see.
Captain Beefheart. It’s great music, but it is ugly.
Wow, that was…um…interesting.
In other news, I think I saw those guys in my last WoW raid.
So, since the topic is “Bo’s Favorite Music”, would y’all just like to browse my collection, or did someone have a question?
William Bolcom, “12 New Etudes.” To me, it’s just random notes, like Bugs Bunny chasing Pepe Le Pew over the keyboard.
Allow me to present William Bolcom at his finest, with Three Ghost Rags. The man can compose wonderful music…but somewhere along the line he experimented with…well, whatever the hell it is those etudes are supposed to be.
(“You call it wonderful, I call it crass.”)
Semi-recent Cracked. I have #3, but I don’t think it’s his most difficult album nor that bad.
Metal gets kind of pedantic: “This is blackened death metal, not black metal! No, I think it’s extreme technical viking death metal!” Nevertheless, Slayer is not death metal by almost all standards.
Dubstep is often listenable, I just don’t get why there needs to be a new genre that doesn’t offer much of anything new. As far as electronic music goes, I can think of less accessible genres.
I successfully guessed what you linked to! Where’s my prize? A lot of noise is somewhat listenable; Merzbow is the extreme end of the spectrum.
