I have to give up at this point if even the members of DOA don't have copies of their own music and if no one else if willing to help me. The third release was either Runnin Scared or the self-titled album (Marked For Death). My guess is that the self-titled album was Problem Child and Marked For Death thrown together.
I'm assuming you have the DOA tapes I take it. And know all about the DOA discography.
