So it seems that after 15 years someone finally tracked down a scan of this, and it's now on bocpages.
https://bocpages.org/wiki/Marcus_Eoin%27s_Campfire_MixtapeIt was in Dazed and Confused after all. The included illustration is wild. At first i thought it was by Mike, but alas not...
I guess this means I didn't make it all up
I've posted about it on other threads, but I should add here that Mike himself helped finish off this mixtape and sent me the final couple of tracks that were basically impossible to find back then, with the note that he was uncomfortable with online filesharing of music and that they were only for distributing to the "good guys at twoism". Now the whole thing is on Youtube ¯\_(ツ)_/¯
