I tried to submit this band several years ago and it was rejected with the following note: "Peter Rohdin himself has stated to me personally that they never released anything." by moderator Porman.

I don't doubt both his and Mr. Rohdin statement, but he was maybe thinking about their solo releases, not splits and compilations, because this split-LP certainly exists:
https://www.discogs.com/Various-3an/release/7256580 and https://thecorroseum.org/comps/3an.html
One of the bands from the compilation (Trace) was accepted at the same time: https://www.metal-archives.com/albums/T ... Aan/510749

The songs:

This seems like a valid release, and it is metal. It's not even blacklisted! Go ahead and submit.

Thank you for the swift reply, I have resubmitted it.
