TV On The Radio-Desperate Youth, Bloodthirsty Babes
The National-Alligator/Boxer (already been mentioned, phenomenal stuff)
Sigur Ros-(), Takk (gorgeous, dreamy Icelandic post-rock)
Mew-And The Glass Handed Kites, No More Stories...
Surprised a thread on hipster music could go 3.5 pages without someone mentioning Radiohead.
Individual tracks I've been binging on lately:
Ride-Vapour Trail
School of Seven Bells-Half Asleep
Polvo-Beggar's Bowl
