Rory Salter is a musician, artist and technician living in London. He has released albums under various projects with Alter, TakuRoku, Infant Tree, Teeth, MAL, Bison, Kashual Plastik and more. His music is formed through experimentations with acoustic & electronic instruments, faulty technologies, cassette tape, feedback and voice; motivated by a relationship to changing and chaotic environments, objects and walking.

Ecka Mordecai is a British artist based in London. Situated between sonic, performative and olfactory disciplines, her work is driven by sensation: entwining cello, horsehair harp, voice, eggflute, scent and improvisation into time-based objects expressive of emotional complexity.

Both intimate and exacting, this body-driven practice defies formal constraints, undoing the limits of genre and allowing for works such as Aequill Sound, a line of niche perfumes inspired by elements of the East London soundscape, or Promise & Illusion (Otoroku, 2022), the album in which Ecka explores myriad internal states using the compositional device of a creaking door hinge (or charniére).

Performing since 2010, Ecka has appeared alongside the likes of David Toop, Malvern Brume, Thurston Moore, Keeley Forsyth, Ilan Volkov, Ex-Easter Island Head, Greta Buitkute, Dave Birchall and Kate Armitage. She has played at Cafe OTO, BBC Glasgow, Islington Mill and inside a Berlin wasserturm, amongst others. She has projects with Revox tape performer Valerio Tricoli in the duo Mordecoli (The Addiction, Hedione 2022), and in the trio Circæa with Andrew Chalk and Tom James Scott (The Bridge of Dreams, Faraway Press, 2019).

Derek Baron is a composer, writer, and teacher from Chicago and New York. They have released music with Penultimate Press, Regional Bears, OtoRoku, Recital, and other labels.
