Hm, where to find out this two releases?

No where i think !

Any info about them - why are they so rare?

Maybe not exactly you answer me, but smbdy, who knows and coming in this topic can clear the situation (in ways such as how many copies was, how good they was - maybe band exterminate 'em at the beginnig of release, and so on...)
