I don't have 100% clarification, but what I remember, is that it is release based on Spasm, with adjused track order to fit LP format. And most notably, that both this, and Victory Through Violence LP on MdP sub-label Robben Island Records, was actually bootlegs that band members didn't know about.
I remember when I sent them letter asking details about the LP's and they had never heard about such releases. My impression was that they wrote label and got some copies and that may be reason why it's listed as "Partially Unofficial" in discogs. Of course, this all happened already 15+ years ago, so memories are vague.
