Although Oxford-born musician Jonny Greenwood is best known on the world music scene as Radiohead's charismatic guitarist, he has also made himself an enduring name in the field of film music over the last two decades. Greenwood, who was born in 1971, has created a unique voice in both rock music and the world of cinema with his ability to play many instruments such as guitar, violin, ondes martenot, xylophone and banjo. Their paths with film music crossed significantly thanks to director Paul Thomas Anderson, with whom he had a long-term collaboration. The music Anderson prepared for the 2007 film There Will Be Blood created a great impact with its structure that combines classical music and contemporary experimentalism. Greenwood blended string instruments and electronic elements so masterfully in this score that many critics considered the score a work that can be listened to independently of the film. This creative partnership with Anderson continued in the films The Master, The Hidden Flaw, Phantom Thread and Licorice Pizza. Phantom Thread, in particular, stood out as a subtle and melancholic work that showed the maturation of Greenwood's composition. An important element that shapes Greenwood's musical identity is the courage to think outside the box. The fact that he is one of the few names who effectively uses a rare electronic instrument such as the ondes martenot in both Radiohead recordings and film scores reveals this courage. The fact that he was ranked 48th in Rolling Stone magazine's list of the best guitarists of all time also confirms his place in rock music. Greenwood, whose contributions to the world of cinema are not limited to Anderson films, continues to stay current with his music production for the 2025 production of War Upon War. Greenwood, who embodies the characteristics of both a rock icon and a serious film composer, continues to be one of the rare artists who knows how to carry these two identities without ever separating them from each other.
