My favourite concept album, and in my top 10 of all time too. Have you got the Steven Wilson remix from a few years back? It's very good.

I loved the interview with Anderson when people were digging at him, suggesting Aqualung was a concept album, he said he would "come up with something that really is the mother of all concept albums" and made TAAB.

A more recent concept album that I love is the Mastodon album Leviathan. It's based on Moby Dick by Herman Melville. It's heavy af, but brilliant!
