You know I've been a voracious reader most of my life but have never really delved into music/bands literature, for me it's just playing and enjoying the music without needing to know all the details.
I've learned more history about bands from music forums than I ever would have searched out for myself, sometimes I have a greater appreciation of what transpired to give us a classic album other times it tarnishes how I feel about some artists even though I know you should separate the work from the person.
I do still have a biographical account of BTO my Mom gave me back in the 70's Riff but I don't think that's what you are looking for.
