A neural net-generated version of the overtone series is juxtaposed against the mathematically correct version, creating odd beatings and dissonances. These are then algorithmically sequenced.

Composed with Brain.js and Max/MSP.

Machine Learning-Induced Beating Sequence

Performed at the Festival of Laurence Crane: A Tribute Concert on Monday 18th October 2021.

The title is an accidental pun on Laurence’s Bobby J for electric guitar. I was chatting with Patrick about putting the piece together and told him we might both have to muster up our best Bobby D impressions (aka Bob Dylan).

Program Notes:

While seeking to expand on the concepts and material found in the original iteration of Spate, I was immersed in its erratic, panicked atmosphere. I became obsessed with the idea of frantic, futile solos lashing out violently from silence with such constant intensity and fervor that they resulted in a kind of horrified stasis, a unit of grotesque and vicious sustain, striving endlessly but going nowhere, grasping desperately at nothing in the pursuit of a distant unseen hope. Spate III furthers this obsession and explores the coalescing of individual "popping" grains, collectively evolving and progressing from individual, ultra-sparse grains/”pops”, to sporadic clusters, and eventually uniting into powerful composite crescendos and undulating masses while celebrating their unpredictable and unstable nature. Often resulting from high pressure friction, these grains evoke a sense of extreme tension, tremendous pressure, and the tempting of a vulnerable threshold, as if an immense force is on the brink of erupting forth.

This piece is for amplified chamber ensemble (no fixed media/live processing/electronics are involved) and was commissioned as part of the LA Phil National Composers Intensive for Wild Up

PROGRAM NOTES

In computer graphics, “raycasting” is the process of tracing the intersection of a virtual surface with an invisible “ray” emanating from a spaceless point within the virtual scene. In Julião Sarmento oeuvre, I constantly sense the shadow of this unseen seer, the eye or lens that possets its existence only through a sensual self-embodiment in the materials it traces. The duality of substance and form that brings to mind, for David Barro, comparisons to Pasolini’s shifting camera angle also evokes David Hume's observation that we have no consistent, unbroken observation of the world. Our perceptual orifices provide an interrupted and inconsistent stream of information from which our perceptions of continuity are reconstructed. In raycaster, the unseen “ray” posits a playful means of bridging the phenomenological gap. I invite the performer and listener to engage in a willful act of self-deception, accepting the possibility of alternate self-realizations through microphones that serve as both substrate and perceptual prosthesis, through speakers that act both to reproduce and to actuate, and through a kind of autogenesis of physical material and monolithic noise into which we can project an alien embodiment.
