Toni Castells (born in Berga, Spain) is an independent artist and composer known for his eclectic and transcendental music that defies traditional boundaries and genres. Currently based in London, Castells’ work blends elements of classical crossover, new age, neo-classical, ambient, and electronica to create music that invites listeners on a journey through expansive, dreamlike worlds, much like the evocative scores of Zimmer and the contemplative pieces of Richter. His innovative approach has led to collaborations with renowned artists and performances at prestigious venues worldwide. His music has been described as "Massive Attack meets Mendelssohn" by Ben Roberts from the music industry magazine London Tourdates and "Morricone meets Satie" by Michael Haas, producer of prize-winning recordings with major classical artists including Zubin Mehta, Mstislav Rostropovich, Daniel Barenboim, Cecilia Bartoli and Luciano Pavarotti. US label Magnatune described it as "Puccini meets Sigur Rós". In addition to his musical career, Castells is a PhD candidate in biomedical engineering, exploring the therapeutic potential of music. His research focuses on the effects of sound on heart rate variability and chronic stress, with a particular interest in music’s role in psychedelic therapy for treating chronic depression. He also shares his expertise as a lecturer on Music Technology at the London College of Music and Imperial College London.
