After reunited Swedish punk-rock greats played a sold-out Terminal 5 show with Ceremony last night, they kept the evening going by playing a secret late-night set at Bushwick’s Acheron, and it looks like it was fun as fuck. Below, we’ve got an 11-minute video of various songs that they played last night, and it starts out with a surprising and semi-improvised but totally impressive cover of “Firestorm,” the immortal kill-everybody anthem from their old Victory labelmates Earth Crisis.

I am now feeling like an absolute loser because I have not yet experienced this reunion firsthand.
