[h=1]Radiohead - The Butcher [/h]i f!@$ love radiohead but most people i know think there to dul (maybe they are but its been 10°C and raining for 4 years)
However, because of the nice tonal qualities of the open string, they are not the first, and they will not be the last, guitar based band to write 90% of their songs around their tuning, and the key that the open string is in.
Examples off the top of my head: Slayer - their "classic era" was everything half step detuned Eb, though they've done some Drop D / Drop C songs. A lot of that "nu metal" genre -- Slipknot, Killswitch Engage, System of a Down, Korn, etc. -- is either drop C or seven string guitar / five string bass tunings (standard with the low B, the many variations of "drop A"). In metal, it seems like a huge amount of the time, the key signature of the song corresponds to the notes of one of the first two strings.
