Alice Cooper by Steve Demorest
Released in 1974 Author Steve Demorest from Circus Magazine writes an excellent book on Alice Cooper.
I would call this the best biography of Alice Cooper so far. Even better than Alice's own "Me, Alice" and Michael Bruce "No More Mr. Nice Guy". Although this isn't much of a behind the scenes bio it's more of the making of the albums. It tells you in detail almost every song on every album. It covers the very first "Pretties For You" all the way up to "Muscle Of Love" album which is the end of the original band.
This also includes some cool black & white photos of the band as well.
