GNP (GROSSEST NATIONAL PRODUCT) : Demo TAPE - 1985 - USA, Alabama, Birmingham - Old tape trading cassette with xeroxed artwork. Not to be confused with the 80's band from Chicago, Illinois. Super rare and obscure hardcore punk with a strong thrash garage influence, totally catchy with cool guitar, good drumming and good punk lyrics. Lots of thrash and a good cover of "I wanna be your dog", all done with lots of power. Make offer.
