Amazon has never heard of Grinder's 'Dead End' album, which is a shame as it's superbeastingawesome. I got it on ebay fairly cheap, but was confused that amazon had never even heard of it...
Amazon is weird - they have some ridiculously obscure stuff like Coven (Washington) and Victims of Internal Decay, but they don't have anything from other bands that if anything are probably more well known. Insanity. And frustrating.
