After surfacing in 2000 with the breakthrough single "Yellow," Coldplay quickly became one of the biggest bands of the new millennium, honing a mix of introspective Brit-pop and anthemic rock that landed the British quartet a near-permanent residence on record charts world-wide. The group's emergence was perfectly timed; Radiohead had just released the overly cerebral Kid A, while Oasis had ditched two founding members and embraced psychedelic experimentation on Standing on the Shoulders of Giants. U.K. audiences were hungry for a fresh-faced rock band with big aspirations and an even bigger sound, and Coldplay were more than happy to take the reigns.
