Saw Boris today with a friend and I'm glad I found my earplugs. My friend couldn't hear anything for a solid 20 minutes after they finished.
We hung around after so he could finish his bar tab and offered to help them tear down since they asked some guys that worked there for help and they just responded with, "not my problem." But I think Wata was afraid we'd try running off with the gear or something.
They were already out of ECT's by the time we showed up.
Side note: Earth were amazing and incredibly heavy sounding. The funniest thing was watching people that were trying to head bang to a 15+ minute song that never picked up tempo.
