Sergio Díaz De Rojas (b. 1994) is a pianist, composer and sound designer from Lima, Peru.

Raised in a family of artists, Sergio’s musical path began under the guidance of his great-aunt Elsa, who introduced him to Bach and Chopin when he was eleven.

Though classically trained, his artistic trajectory shifted during his university years, when discovering musicians like Nils Frahm, Max Richter, and Ólafur Arnalds opened a new horizon and quietly nudged him toward composition. Later came Sufjan Stevens and Keaton Henson, whose work carried a tenderness and vulnerability that reshaped his understanding of what a piece of music could hold.

In 2015, Sergio self-released his first album, Unsaid Words. Its yearning arpeggios, evocative melodies and mastery of mood quickly introduced his talents. Pieces like Serendipity and Calmness revealed his knack for pairing neoclassical composition with found sounds, while the mournful cello of Nature nodded gently to 19th-century chamber music. He went on to release three EPs: December 03 (2016), recorded in a single afternoon; The Morning is a River (2017), created with German visual artist Seraphina Theresa and accompanied by slow-moving images, a photo series, and a poem on a limited cassette edition; and Postcards (2020), a contemplative reflection on solitude influenced by the spirit of Chopin and released as a 7-inch vinyl.

With over thirty million streams, concerts throughout Europe and South America, and collaborations with Deutsche Grammophon, 7K!, and LEITER Verlag, Sergio released his third full-length album, Forgotten Fragments, on December 05, 2025, via Nettwerk. The album will be accompanied by two handcrafted vinyl editions, an exclusive CD edition for Japan, and a tour.
