It's no accident that so many fabled rock ensembles have had two contrasting leaders (Lennon and McCartney, Jagger and Richards, Plant and Page, Bono and The Edge) to play off each other and cross-pollinate and, at times, butt heads. But Chris Martin completely dominates Coldplay; there's no yin to his smiley enraptured yang. He's the rock-king superstar the other band members all worship, humbly, as the genius who made their fates possible, and almost every moment of the band's creative energy is organized around what Chris is going to do next: the piano chords he's playing around with, the lyrics he's writing, his endless studio perfectionism. source.
