Patch Notes: Grand River Patch Notes: Grand River An evolving composition recorded in lockdown with piano, synth modules and effects. Grand River is the alias of Aimée Portioli, a Dutch-Italian composer based in Berlin. Her music, which has appeared on Longform Editions, Spazio Disponibile and her own label One Instrument, draws on minimalism and contemporary sound design to create tactile sonic structures that bring an ASMR quality to her ambient music. On this Patch Notes session, recorded in the living room of her Berlin apartment late last year during lockdown, Portioli manipulates a variety of acoustic and electronic sources.
