ANATO is a great album, as is Queen's follow-up, A Day At The Races. That said, I end up listening to their precursor, Sheer Heart Attack more than either one of those albums because I feel it is a lot less polished and captures a more natural type of energy while setting the template for these later albums. IMO, ANATO & ADATR don't have a single note that wasn't written down and practiced a thousand times before recording. Sheer Heart Attack just comes off as more organic to me, and it rocks!
