So y'know how Cannibal Corpse's "Hammer Smashed Face" is an excellent death metal song, and Yoko Ono sucks super bad? Well, it shouldn't come as a huge surprise that when you add Ono's vocals on top of an instrumental version of "Hammer Smashed Face," the result is seriously not that great.
The yelling comes from Ono's exhibition at the Museum of Modern Art in 2010, I believe titled Voice Piece for Soprano, which didn't make the museum very happy.
