Hi, I'm Reilly Spitzfaden! I'm a composer and programmer who likes noise, obsolete media, electronics, and nostalgia.

Afterimage from
I have been drawn for years to Reilly's playful, absurdist, and critical lens towards humanity's now near-inextricable relationship to technology in the 21st century
—J Clancy, BlackBox Ensemble
BlackBox Ensemble performed my composition Afterimage from at a concert in Brooklyn, NY. Percussionist J Clancy had these kind words to say about the piece.
You can watch a score follower video of an earlier recording of the piece below:
If this reaches you
My piece If this reaches you is on Apply Triangle's 2024 album Oxalis Triangularis — I was one of the composers selected in the group's call for scores. The album is a 3-CD release, and my piece is on volume 2.
Contemporary classical magazine I Care If You Listen did an intervew with the group, and described my piece as having
a retro-futuristic vibe with electronic samples from distorted fax machines, maritime radios and walkie-talkies
I also wrote a blog post about composing the piece.

Reach Through
The TaPIR Lab at the University of Toronto commissioned me for the 2023 Composer in Residence Concert. I wrote Reach Through for percussion quartet, with each performer using the accelerometer/gyroscope data from a mobile phone to trigger and control sounds in Max/MSP.
Here is the premiere at Array Space in Toronto.
