The cassettes are their 6-song Demo TAPE, the famous "No Core" Comp. TAPE, the Caroline "6 songs with Mike singing" TAPE version and a 4-song practice (from the old TAPE trading days).
About the vinyls, you know what they are... 

For some reasons, I've sold "Animosity" LP and "Technocracy" 12" in the 90's, and I never bought them again?? One day maybe...
