The Pyramid has been hopping with free Friday night shows by pop-punk band Dameht (“The Mad,” backwards), who currently have a residency at the iconic Avenue A club. They’ll be there — featuring guitarist Lucas, above , right — for at least the next two Fridays, said Clayton Patterson, a big fan of the band. “It’s fun and it’s free,” Patterson said. “Drinks are cheap. It’s a great location. It’s the last venue — the last original club — that’s still in existence, that survived the ’80s, ’90s and 2000s.”
