Yeah, I am a diehard Sorhin fan and own all their demo/cds/lp minus the Boxset. I also own the amazing Sorhin sideproject Necromancy.
I take my demo buying/trading very seriously, and most of my demos are 100% real. Of course there are some "possibilities" with some of my demos, but for the "more known" demos like Sorhin one is able to track down others with the demo and compare if I have any doubts.
My Bekhira demo came directly from Noktu, and I got the Sorhin demo from from a diehard collector of 2nd wave Swedish BM.
But I still would rather buy....
Regardless, if you have any items on my wantlist please let me know.
