29. Sigur Ros, 'Ágætis Byrjun'
Beautiful and alien, Ágætis Byrjun was like being plunged into an Atlantis where language, gender and songforms were largely indeterminate. Sigur Rós conjured magic with drones, using strings, brass, electronics and guitars that took Jimmy Page's bowing technique to new heights. But the showstopper was Jónsi Birgisson's otherworldly voice, swooping between tenor confessions and falsetto ballet. Filmmakers Wes Anderson and Cameron Crowe have since used Byrjun in their soundtracks, but it was tough to beat the movies that this music conjured inside your own head.
