Release Info: unknown test press (?, 19??)
Now, for a complete mystery, at least to me. The person I got this from said it was Finnish and from the 80s. At least some of the last song is in English but beyond that I can't make much out. Here's what I can tell you:
1) The sound is heavy hardcore that seems typically mid 80s. To me it sounds more Japanese than anything but hardcore is not something I'm particularly interested in or knowledgeable about.
2) The only markings in the dead wax are "MPS A", "MPS B" and something that looks like "OP13".
3) Side A has two distinct tracks and plays at 45. Side B has 3 and plays at 33.
4) Track #3 (the first on Side B) has "5-4-3-2-1-0 Ignition Liftoff" near the beginning which should be memorable if you're familiar with the song.
Take a listen and if you know what this is I'd really like to know.
