There's an album for Simon and Garfunkel live at Madison square garden. I think I only really love it more than most of their other stuff because it's the album I grew up on and it's got all the classics. Unfortunately I couldn't find it on Spotify, but it's probably out there.

It's not an album necessarily, but there is a Portugal The Man live sort of half documentary half album that's done acoustically. It's awesome, I think it really highlights how eclectic they are as a group.

Similarly, not an album, but there's a few accoustic songs done by Manchester Orchestra in one sitting that's on YouTube and it's just absolutely gorgeous. It's my favorite songs of theirs and it's just beautiful.
