...debut disk recorded in roughly 48hours by these hepsters from th' back streets 'n alleyways o' th' late 6ohs...takin th' heavy blues rock then prevalent 'n uppin th' riff'n thud quotient to create what many cats offer as th' first heavy metal elpee...that assumption could be true then again debate is always ready to be had...what is certain is this is th' way they saw 'n heard th' sounds around them in cellars 'n backrooms 'n interpreted them accordin'ly...very cool wax 'n still makes for a goodly poundin lugfull...
