I had considered several of the Tull albums for my list. Thick As A Brick is very good while Too Old To RR .... comes with a nice graphic comic of the story . The Lamb Lies Down On Broadway has piqued my interest. Not a big Genesis fan but I'll have to grab a used CD next time I see one.
Yeah,as single songs go, Bohemian Rhapsody is probably the epitome of a rock opera.
I have to ask, for those that agreed with albums mentioned so far, how does American Idiot fit in? I don't see Green Day mentioned very often in the music room.
