Razor's edgeBands like PA's No Retreat and NJ's Lifeless come to mind when listening to Reserving Dirtnaps. Both bands I like a lot, so I have no problem here. Reserving Dirtnaps can hang with the best of em, their first EP is solid from start to finish, I love it, a very impressive effort. I imagine their hometown shows have some crazy violent pits. If you like it hard, tough and violent, check out Reserving Dirtnaps. Hopefully they'll make it out to Europe someday, I would love to see these guys at a show in the Ruhrpott area in Germany.
So many I wish were dead
Instead keep my soul bound to flesh
Nail of breath
*update: Brandon from RD has informed me 'reserving dirtnaps' means something like 'setting up someone's death date'. *
