Off the list:
The Caretaker, after Everywhere At The End Of Time was a devastating realization of what they'd been doing the whole time, and superlative-obsessed reviewers took notice.
Frightened Rabbit, whose recognition was unfortunately well-demonstrated when their lead singer jumped off a bridge. Honestly, it was the world's least surprising suicide. The man wrote a song about it. Same bridge and everything.
My Morning Jacket, a psychedelic rock act well-known enough to make a McSweeney's list of "what your favorite Sad Dad Band says about you." (Viz: "you know how to cook an eel.") The album Z absolutely rules, and you have to remove the skin and rinse out the blood.
