I feel like Alive should count even though its not new material. It's so good and different take on their own tracks.

Congratulations, you found the "everything they did after Homework sucks" snob.

I think it's a little more complicated than that. Human After All was widely panned on release (and in my opinion remains very hard to listen to), but then was "rehabilitated" by the Alive 2007 live album. And Random Access Memories always felt like it lacked the energy of their earlier work, sort of like lounge music. Just one opinion, but not necessarily snobbery.
