Might have witnessed the band breaking up on stage
After the encore break, the drummer and bassist refused to re-take the stage. The two guitar players did one song together and then seemed confused and said "I guess that's it for tonight." He then questioned whether they were even still a band and then tossed his guitar into the drum set. Also, this was by far the loudest concert I've ever attended. Earplugs were mandatory and still not enough.
