One of my favorite albums by Alice Cooper is definitely his first, Love it to Death. Back in 1971 the band had not fully gotten into the dark gothic shows that would come along a few years later but you can already see the creepiness starting to show.
This isn’t the best video I could find on Youtube but I prefer live Rock & Roll to recorded any day of the week. It’s a video of Alice & band performing in Detroit in 1971.
