I lived in Baltimore during my formative years and punk/hardcore music always seemed to be a "step child" to the city's burgeoning metal scene. The Marble Bar closed in the mid-80's and most of the punk bands played D.I.Y. spaces or DC after that. It seemed like it wasn't until Chris X. opened Reptilian Records in the late 80's that punk bands started coming back through on a regular basis.
I'm pleasantly amazed at the scene that seems to have sprung up since I left town and Pulling Teeth and A389 Recordings seem to be major players. I hadn't heard Pulling Teeth prior to seeing them at MDF but I'm definitely going to have to check out their back catalogue.
