I've never really bought into the revised historical importance of this record - in fact I think it is mostly a pointless exercise to go back to the 60s (and even the 50s?) and call early rock & roll stuff proto-punk, because it reduces the roots of punk to very noisy or loud rock & roll and ignores the glam rock and other 70s movements that shaped the attitude and sound of punk.
That being said for a rock & roll album from the early 60s this is an interesting artifact, the lead singer has tons of energy and the 4 original songs are all great tracks about ghouls and witches and murder which is pretty awesome.
The covers really let this down as they don't carry the same energy or fit as well with the overall sound. But despite this it is definitely worth a listen for Psycho alone which is a 11/10 track.
