Music, stemming from college students getting together to form a band, in hopes of becoming rockstars, but doing so by straying away from any mainstream styles and doing so by being jammy and being "unique."
This ultimately results in becoming a typical college band -- having
piss-poor production qualities (always done in a
weekend's time at a crappy local studio), slightly
out of tune vocalists and/or guitars, acoustic guitars, and lots of jamming. 99% of college bands belong to this group, which is why 99% of successful bands do not come from college formed bands.
