BLUE CHEER Vincebus Eruptum (Proto-Metal Classic 1968 UK 6-track MONO LP, one of the heaviest psych debuts in rock history. This band pretty much defined "Power Trio", naming themselves after the most potent brand of street acid, these guyswere so fierce that rumour has it a dog once died on stage at one of their concerts. The summer of love was over! This is the first issue with black & silver labels & an ultra cool, mean looking front laminated sleeve in dark blue & silver tones.The cover shows some minor discolouring and edge creasing to the laminate and considering its age it remains in very good condition. The vinyl has a few light marks and spindle wear to show careful play during its over fifty-five years in the wild!)
