Bio

Berlin-based composer and musician Aimée Portioli, aka Grand River, takes a painterly, emotionally plugged-in approach to her music and sound art that has seen her develop a distinct signature over the last decade. She’s put out an acclaimed run of releases on a number of prestigious imprints, including Editions Mego, Ghostly International, light-years and Spazio Disponibile, and in fall 2026 will unleash her new album Temporary, a direct and focused set of wordless electro-acoustic pieces hinged on the interplay between Portioli's guitar work and synthesiser processes. In parallel, she also develops multichannel installations, such as Symphony for Endangered Birds, which debuted at Essen's Museum Folkwang, and Tuning the Wind, which was issued in 2025 on Umor Rex. Portioli continues to perform at festivals and venues across the world, appearing at Berlin's Atonal, Paris's Centre Pompidou, Montreal's MUTEK and CTM Festival, as well as London's Barbican Centre.
