There obviously has to be some kind of rereleasing going on, since it says 1996 2000 2002 on the back, that could explain why i kept seeing 2002 as release on several stores etc. Of cousre its been released in 96 there is no doubt in that, when its litterally on the back of the sleeve:D
Also about the siren and the papercut sample, those are somewhat common, but back when we didn´t have the official vinyls from joe and when stuff like serato was crazy expensive i spent ages finding different samples and i think i found the origin of the Poa/Bth sample
