That song went on for at least twice as long as it should have.
Otherwise, it was an improvised hardcore song. It sounded like your singer vomiting into a microphone while the band punched their instruments semi-rhythmicly. (Which is to say awesome! )
Yeah, we're actually a blackmetalband, actually about to sign a deal in near-future.
We usually have "dry" rehealsals once a week, and "wet" rehealsals on weekends, when we mostly just screw around.
