About Indexical

Indexical engages the public in radical and unfamiliar artistic work through an ongoing series of performances, workshops, and publications.


Indexical has presented concerts since 2011, beginning in a converted chapel in Brooklyn and relocating to Santa Cruz, California, in 2015. In 2018, Indexical formed a 501c3 nonprofit organization with the intention of providing a permanent home for experimental music and art in Santa Cruz.

We work closely with a handful of artists and composers to develop projects and new ideas over the course of many performances. This has included collaborations with artists such as Happy Valley Band, String Noise, Ghost Ensemble, Séverine Ballon, RAGE THORMBONES & Zachary James Watkins, Ma’ayan Tsadka, Laura Steenberge & K.C.M. Walker, and frequently includes those of us running Indexical.

Our performances sometimes become larger-scale studio projects, released on our in-house record label. Sometimes they’re accompanied by interviews and essays. In addition to studio recordings, we release many live recordings, videos, and live-in-studio performances through our subscription series The Essential Indexical.

In all releases and projects, we are interested in fitting the format of the project to the work, whether that entails a concert, lecture, publication, or custom bug-killing machine.


Indexical is dedicated to experimentation in music. Indexical engages the public in radical and unfamiliar work through performance, publication, documentation, educational initiatives, and discussion. We work with historically, culturally, and institutionally underrepresented artists and build community through long-term collaborative projects.
