"I met Brian O'Reilly when he was Musical Assistant at Iannis Xenakis' center Les Ateliers UPIC in Paris. Brian worked with composers such as Luc Ferrari and Eliane Radigue, among others. I soon learned that besides his expertise in electronic music, he was also a dedicated visual artist. Eventually, we collaborated on a series of videos to accompany my music. What struck me about his approach was the similarity to my methods. The creation and selection of initial source material is careful and crucial. Then there is a phase of controlled improvisation, seeing how the materials go together in sequence and simultaneously. This is followed by an extended period of extremely detailed editing, with an obsession with details of image quality. The excellence of the final product speaks for itself."  - Curtis Roads



"Although Brian's style of work overtly looks somewhat akin to the VJ improvisational style, on closer look (and hearing) it becomes obvious that it comes from the serious contemporary musical tradition. In the search for "new" audio-visual aesthetics, digital tools are giving the artist better access to real-time with a greater level of precision in audiovisual composition. Brian has brought his work into a rare state of excellence."  - Steina & Woody Vasulka
