oh we are talking audio.
Well anything really that has a story throughout. Too many to list, even ?
The Wall, The Final Cut, i mean, if you listen to the Pink Floys guys, ALL their albums are concept albums.
Stuff like The Lamb Lies Down are touted to be albums that "tell a story" but i couldn't tell from listening to it. Joe's Garage is a rock opera, in that every song serves to tell the one story of Joe's misadventures.
Many albums have a common theme and are not specifically rock operas.
what was the point of this thread anyway ?
