Query: Ethereal soundtrack for the new millennium

While it's not immediately accessible like "The Bends" (1995) and lacks the melodic hooks of "OK Computer" (1997), "Kid A" challenges the listener to grow with the band's sound. Defying conventional song structures on most of its tracks, "Kid A" grows more and more enjoyable with each repeated listening. "The National Anthem," with its show-stopping horn finale, is enough to make you stand up and salute. A word to the uninitiated: To fully appreciate the band's aural accomplishment, listen to "The Bends" and "OK Computer" first.
