LightRiders was honored to be a part of this incredible project to bring the Triforium back to life for a three part series in the fall of 2018. Featured in the LA Times and the culmination of a multi-year project, this endeavor revived a decades old, ahead-of-its-time audiovisual structure originally designed and installed by Joseph Young. With new technology (and some old tech), we were able to get the Triforium back up and running for a limited, temporary run. Hopefully, it can be restored to embody the original vision of Joseph Young’s futuristic vision.

From the Triforium Project

“The series, curated by Claire L. Evans and Jona Bechtolt of 5 EVERY DAY and YACHT, is hosted by Tom Carroll of TOM EXPLORES LOS ANGELES and made possible with the assistance and support of LA City Councilmember JOSE HUIZAR, the Los Angeles DEPARTMENT OF CULTURAL AFFAIRS, the GOLDHIRSH FOUNDATIONTHE NATIONAL TRUST FOR HISTORIC PRESERVATION, and NOW ART LA.”
