One of the most unpredictable bands on the American indie scene, The Flaming Lips' work is better defined by eras rather than a sound. Having dabbled in everything from psych-pop to prog rock, to esoteric projects like a 24-hour song and world record-setting tour, the group's openness to change is tied to their lasting success. You might not know what a new Flaming Lips song will sound like, but you'll know it's them as soon as you hear it.
