Hanover-based mcddavid is an improviser and performer whose work often leans into playful subversion: he's known for developing extended techniques that can involve not touching the instrument, and for making "chaos poems" and performances using everyday materials like balloons and pipe-cleaners. He's also part of the Mopomoso team in London, and has composed two audience-participation operas for the series.

Within the world of freely improvised music, mcddavid has longstanding collaborative ties with Jörg Hufschmidt (they've known each other since the late 1990s and later formed the New York Guitar Duo on acoustic guitars). He's also described as an independent filmmaker, and has participated in multiple project-bands and collectives.

On Die 3 Diven's RCHTN MTNCHTN, he appears as DD / Dietrich Diva, credited with acoustic guitar, balloons, and castanets-a concise snapshot of his sound-world: instrumental technique mixed with tactile, object-based performance.

Andreas Gogol (often credited as AGogol, and on this release as AD / ACID DIVA / DA) is a Berlin-based artist and musician born in 1968 in Braunschweig, living in Berlin since 1996. His background spans multiple disciplines: he holds a Diplom & Master of Fine Arts in film & photography (HBK Braunschweig, 2003), trained professionally as a painter, and has also worked in social care with disabled people-threads that fit his hybrid practice across image, sound, and performance.

Gogol has been deeply involved in experimental music culture as an organiser as well as an artist-co-organising the "electronic church" space for electronic/improvised music in Berlin (2008-2009) and working on CTM Festival coordination (2008-2012).

A notable strand of his work is expanded cinema with filmmaker Telemach Wiesinger, combining 16mm film and live analogue sound in performances that continually reconfigure short film/audio sequences; one programme is documented as having won a Team-Work Award at Stuttgart's festival for Expanded Media.

On RCHTN MTNCHTN, he's credited with electric guitar, electronics, and voice, aligning the project's trio-guitar core with noisy, textural, and performative electronics.

Jörg Hufschmidt is a Hanover-based sound artist whose work moves between painting/drawing and sound performance, often treating improvisation as a meeting point for visual and sonic thinking.

His biography reflects that cross-disciplinary arc: after training and early study in design, he shifted toward fine art, developing focus areas in drawing/graphic work, sound art, and free improvised music. He founded ensembles exploring instrumental and object-sound with electronics, later deepening the intermedia angle through projects that integrate performance and visual components.

Hufschmidt also co-founded and sustains long-running infrastructure for the scene in Hannover-particularly through Atelier Grammophon and the association Dingding e.V., curating exhibitions and presenting concerts (often with international guests) in free improvised music.

On RCHTN MTNCHTN, he's credited with acoustic guitar, "sounddrawings," and objects, and also appears in the recording credits for the live Berlin track-fitting for an artist whose practice explicitly links drawing, performance, and sound.
