“Mutations” are artistic organisms, of unlimited duration, that generates a new work every new bounce/performance. Composition is done by real-time interactive computer systems with (or not) live interaction of the composer with field recordings from the DNArchive Project, in audio and image. A selection of world walkscapes in transcultural cities gets blended/mutated by a special digital compositional process, that transmutates the sound and image into a transgenic work. Acting as a DNA enzyme, the compositional process acts combining randomness with sound/video processing to digest 360 and ambisonic recordings of transcultural places. This is an analogy to the genetic process of mutation, that produces diversity in biological organisms. This work produces diversity in artistic landscapes, in real-time for each performance and specific for a site-installation system. Each mutation carries a place/date/time in its name. In this version Mutation 18/07/2025, it will be is a sonic photography in which Oslo (Norway), Porto (Portugal), Medellín (Colômbia), Rio de Janeiro (Brazil), Plymouth (UK), New York (US), were mutated and combined into a new landscape of 5 min and 4 continents.This work is part of the Transeuntis Mundi Project, that brings the power of memory, ancestry, language and migration to a practice-led artistic research about transcultural people and cities around the world, as a process of recognition of historical migration and diasporic events. This work is in progress, alive, in mutation.
