Long-form (~45') live coding performance using Gibber, featuring both live music and shader programming.

In this piece that I composed and conducted, titled Ambiguous Suggestions, I conduct the CREATE Ensemble by creating two-dimensional gestures that are transmitted to personal mobile devices and subsequently interpreted by ensemble members. These gestures are sent to anonymous numbers via the conductor's interface, forcing me to think of solely of compositional shape rather than instrumental timbre. In the screenshot, my back is to the ensemble t o emphasize my disconnect with them. The software component was realized using Interface.js.

Group live coding performance using Gibber, performed with the CREATE Ensemble and titled Passages. The piece was an exquisite corpse, where code fragments were passed from performer to performer using Gibber's chat system, modified, and executed. From a review by the Joseph Woodard of Santa Barbara News Press:

To those of us in the audience not "in the know" about the program, it seemed odd to find several people cradling jumbo laptops scattered throughout the house, as if their nerdy umbilical attachment to their computers continued into the concert hall experience. The truth became known, though, with the performance of the piece "Passages," by the CREATE Ensemble. Said ensemble, being Fernando Rincon Estrada, Anthony Garcia, Charlie Roberts, Luke Taylor, Tim Wood, Karl Yerkes, and director Matthew Wright, produced a live, real time and spatially dispersed ensemble opus. Their faces were projected, via computer cams, onto a large screen on stage, further blurring the elements of stage, house, live interactions and computer coding as they went. With a touch of theater, they slowly closed their laptop lids, shutting down the in sync, capping an altogether entertaining and conceptual high point of the night.

The first Gibber performance, with the CREATE Ensemble. Each performer wrote code on his/her individual laptop, and auditioned the results with headphones. When satisfied, they transmitted the code over the network to a central computer connected to the house projector and speakers. The code that each member submitted was displayed in a running tally, along with chat communications between performers.

Improv for Liquids and Electronics was an audiovisual performance combining liquid projection techniques, computer vision, and generative music. I spent most of the performance create visuals using a combination of oils, bases, acids and pH indicators while the resulting projection was analyzed for color content and blob detection. This analysis was in turn used to feed generative music created in ChucK.
