I'm sort of a sucker for concept albums and this definitely fits into the category.
Razia's Shadow is the very ambitious second album from Forgive Durden (which is now officially only comprised of one dude, Thomas Dutton).
Razia's Shadow is a musical. At first I was a little skeptical because it seemed a little pretentious but I got pretty excited when I heard about the ridiculous amount of guest vocals the album features. People that make an appearance: Casey Crescenzo, Lizzie Huffman, Max Bemis, Chris Conley, Danny Stevens, Brendon Urie, Dan Young, Greta Salpeter, Nic Newsham, John Gourley, Kris Ayana and Shawn Harris.

I think it's definitely worth a listen. It's different.
