I bought tickets to this show to see Diarrhea Planet. They rock out pretty hard on the couple tracks I've heard and their website describes their sound as "The Ramones holding Van Halen hostage with an arsenal of fireworks and explosives."
The So So Glos are a punk rock band from Brooklyn who I don't know much about. But the Great Scott is a cool venue for a show.
The show starts at 9pm. Plan to meet at the Great Scott at 830pm. It's a pretty small bar. We can meet to the left of the entrance near the bar, there is an island/high-top table.
