A horrible experiment in which it was discovered that otherwise talented musicians could create really shitty music. Phenomenal albums if what you like is really fast songs with no apparent melody because lisening to d-tuned garbage played at 166 bpm makes you "hardcore."
"Hey, I want to get back at my more talented friends for being more talented than I am. How can I make a total embarrasment out of myself?"
"Get all these great musicians together, record a really crappy album, and sell it through Wal-Mart. And use a really stupid band name - Superjoint Ritual sounds good. If that doesn't show the world what a turd you are, then nothing will."
