has been a member of the Conlon Foundation from 2000 to the present, with different tasks, among which, being Chair for 12 years.

Recording one-arm bandits in Las Vegas for “…and god invented dice”,   developing new instruments like the soundwheel, plexiphone, wind-twirler, making a sound painting of the of (Tesla) plasma lamps in slow motion, “Neon Study #1 for Ensemble Modelo62, belong to the work of a composer with a lack of adherence to convention, but who at the same time, cherishes histories and traditions. 

Visual sources are important inspirations - modernism of the XXe, patterns from/of many cultures. With “Period Point Blank”, she embarked on making video in her work, and has gone further with ‘experimental imagery’ for her Bowed Electrons Festival Online 2021 and 2022 concerts.

An American-Dutch composer who left the US in '69 after singing in the band Dan Hicks and his Hot Licks, she was briefly a singer-songwriter in London and long a dance musician and 'rhythm for dance' teacher at the Hogeschool vd Kunsten Amsterdam. In this period, she studied piano with Willem Brons at the Conservatory of Amsterdam, when she truly 'heard' new music for the first time.   

At age 50, she embarked on a career in composition, studying with Klaas de Vries at CodArts Rotterdam, graduated with the Composition Prize and has been composing ever since.  Masterclasses were done with, among others, Richard Rijnvos and Toshio Hosokawa.

Boris Bezemer (algemeen lid)

Boris Bezemer's music strikes an expressive balance between structure and chance, the standing leg and the playing leg. Growing up observing life and biking through the rainy forests of Gelderland, he would play guitar, program computers and dream of being an inventor.


He moved to Amsterdam where he now surrounds himself with electronic music, accordion music, organs, orchestras and opera: all attempts to answer the desire for the unfamiliar, that element of strangeness that's so essential for romance. Bezemer composes worlds of sound accommodating multitudes that flow continuously, comforting with turbulence, accepting chaos and combining scattered voices into magical environments.

Daniel Schorno

The composer DANIEL SCHORNO originally hails from Zurich/Switzerland, studied composition cello and conducting in London with Melanie Daiken, William Mival and Lawrence Leonard and electronic and computer music in The Hague/Netherlands with Joel Ryan, Clarence Barlow and Paul Berg. A love for experimental interactive live-electronic music has made Amsterdam his home for over a quarter of a century.

Invited by Michel Waisvisz he lead STEIM – the renown Dutch STudio for Electro-Instrumental Music - as Artistic Director twice in the early part of the 2000’s. Daniel established STEIM’s digital artist-in-residence educational programme prior to this and acted as one of the studio’s senior artistic consultants up until 2012.

Daniel Schorno’s highly idiosyncratic approach to compositional procedure and integration of eponymous [personal] instruments is reflected in a musical noosphere characterized by razor edged real-time digital sonification and interspersed by the occasional clamour of one-of-a-kind crackle scorpio & dragon sculptures.


Collaborations with international musicians, artists, choreographer, ensembles, artscience and festivals include Christina Viola Oorebeek, Ana Rewakowicz, Frances-Marie Uitti, Garth Knox, Joel Ryan, Dan Koppelman, Ernest Rombaut, Pascal Boudreault, Haraldur Karlsson, Jan St Werner, Jason Kahn, Laurens Tan, Toon de Zoeten, Maria-Ines Villasmil, José Navas, Frank van de Ven, Keith Bramich, Insomnio and Nieuw Ensemble, EMW Shanghai, Forum Neues Musiktheater Stuttgart, 2N2D Odessa, Raftlost Reykjavik, xCoAx’13-22, ICMC’12 &’16, LadHyX/École polytechnique Paris, NCCA Kaliningrad, Caja Ludica Guatemala City, Windybrow Johannesburg & others.

Under the alias ‘zitegeist’ Daniel has travelled the globe performing on vintage analog and digital eponymous instruments.
