My entire library. Because I also happen to enjoy Brand New from time to time (i.e. only in concert because their records pale in comparison).
But seriously, try:
I Love You But I've Chosen Darkness
Editors
Jets to Brazil (probably their latest record)
Modest Mouse
Honestly, Slint would probably be a good suggestion.
Cursive
Margot & the Nuclear So-and-So's
The Pixies
And there are probably more, better suggestions, but this was just a quick perusal of my library.
Also, it'll probably be a longshot, but Neutral Milk Hotel. Jesse Lacey is known to cover songs like, "Oh Comely" and "Two Headed Boy Part Two" in concert and insists that In the Aeroplane Over the Sea is "the most beautiful record ever made."
