Aimée Portioli (b. 1985), known as Grand River is a Dutch-Italian composer and poly-instrumentalist producer based in Berlin.

While mainly connected to the fields of electronic music and sound design, her compositions transcend these genres.

Influenced by classical minimal music Grand River’s work integrates a large variety of sound structures and symphonic calculations in which she crafts absorbing experimental and ambient narrations combining traditional composition with contemporary sound research.

Her first release “Crescente”, was released via Spazio Disponibile in 2017 and has been named as one of the best releases of the year by XLR8R.
Since then, her work has been presented in festivals and venues across the world such as Berghain, Mutek, Mapping Festival, Nachtdigital, Le Guess Who, De School, Paral·lel Festival, The Labyrinth, Funkhaus, and many more.

Together with the visual artist Marco C. she sometimes presents the A/V performance called “0,13%”.

Her full-length debut album “Pineapple” followed in 2018 on Spazio Disponibile along with participations on Ghostly International and the Australian Longform Editions in 2019.

Since 2016, Aimée also runs the record label One Instrument.
