Coldplay is a British rock band formed in London in the late 1990s, best known for a melodic, piano- and guitar-driven sound that blends alternative rock, pop rock, and elements of electronic and ambient music. The group rose to international prominence in the early 2000s with emotionally resonant songs characterized by soaring melodies, anthemic choruses, and introspective lyrics. Over the course of their career they have experimented with production styles and instrumentation, incorporating electronic textures, stadium-sized arrangements and collaborative features while maintaining a focus on accessible songcraft and emotive vocal delivery. Coldplay has been active as a recording and performing act from the late 1990s into the 21st century.
