Radiohead! Proceed with caution, not all of their albums are rock music.

I'm one of the weirdos buying into the hype of black midi, BCNR and Squid as well. Give them a shot. black midi is probably the most experimental of the bunch.

There's also Interpol, Arcade Fire, The National: the usual suspects. Dismemberment Plan, The Mars Volta, Porcupine Tree. Some more recent indie rock: Pinegrove, Hop Along, Indigo de Souza.

Your mileage may vary, of course, but they're some of my favorites.
