City String Ensemble (CSE) is a London-based, multi-genre string group redefining what a modern string quartet can be. Fusing classical technique with contemporary energy, CSE is known for their striking arrangements of pop, rock, film, and anime music, featuring extended techniques like rhythmic chopping, ghost notes, and percussive bowing not typically heard in traditional string playing.

Since 2016, CSE has grown from a sought-after string quartet into a full-scale string orchestra, performing across the UK for concerts, celebrity events, and high-profile premieres including the world premiere of Bridgerton Season 2 in London. Their acclaimed live shows, including their Taylor Swift, Coldplay, anime tributes, are known for breaking classical norms through interactive audience moments, improvisation, and immersive energy that bridges the gap between concert hall and festival stage.

CSE regularly records and releases their own classical interpretations of modern music, with streaming numbers currently exceeding half a million on Spotify. Their latest release, CSE Performs Taylor Swift follows the success of their Best of Anime EP, with another recording project already in the works.
