44. Boards of Canada, "An Eagle in Your Mind"
The Scottish electronic duo of Michael Sandison and Marcus Eoin arrived out of the blue – two rural brothers graduating from homemade tapes to their hugely influential debut album Music Has the Right to Children, on the U.K.'s Warp label. It's a post-Aphex ambient swirl of distressed digital and analog sound-smudges – "dirty music," they called it. "An Eagle in Your Mind" unfolds over intricately textured percussion – Sandison's girlfriend's voice, mutated in the studio – and a voice-over from a documentary about the family life of otters.
