Loop-Copy-Mutate: Music from People and Places


(2) flyerLCM_voor_300

Loop-Copy-Mutate is a piece of music whose audience is an essential part of the performance.

Loop-Copy-Mutate: Music from People and Places is a new project by the Genetic Choir, which will yield a year-long series of concerts in 2017. Led by singer and artistic director Thomas Johannsen the Genetic Choir directs our ears towards something urbanites often take for granted: city sounds. Together with laptop artist Robert van Heumen, programmer Stelios Manousakis, and the public, the choir transforms sampled city sounds into voice and music compositions.

The première of Loop-Copy-Mutate was held on 2 July 2017 in the new Noord/Zuidlijn metro station beneath Amsterdam Central Station. In the weeks preceding the concert the Genetic Choir held ‘sound walks‘ around Amsterdam CS, asking travellers, passers-by, and people from all over the world to listen to the stations’ sounds as if they were a symphony, inviting them to add their chosen sounds to a musical database. During the concert on 2 July, the public decided which sounds were used as part of the event.

We invite people from all over the world to enrich our online database with sounds taken from their own surroundings. The choir sources its sounds from this database for live performances, so the public is involved in shaping the compositions.

ROBERT VAN HEUMEN is a composer and improvising musician using an extended laptop-instrument to perform highly immersive and hyper-dynamic electro-acoustic music. Van Heumen teaches at the Conservatory of Amsterdam and previously worked as a project manager at STEIM .

STELIOS MANOUSAKIS is a composer, performer, sound artist, and researcher, collaborating within the fields of art, science, engineering / composition, performance, and installation. He uses software he designs himself, merging algorithmic finesse with the immediacy of audience participation, and the expressiveness of improvisation.

STEIM (the STudio for Electro-Instrumental Music) is an independent electronic music center in
Amsterdam dedicated to live performance, supporting an international community of performers, musicians, and visual artists. STEIM has provided us with in-kind equipment and performance space for the project.

BIMHUIS is the prime jazz and improvisation venue in Amsterdam and has generously supported us for the 2 July concerts and soundwalks on Amsterdam CS by taking on the pre-sale and ticketing for us and adopting the Noord/Zuidlijn concerts of Loop-Copy-Mutate as ‘Bimhuis-on-location’ events.
