Sarah Holtschlag’s evocative singing saw over layers of brilliant synth clouds.

After Reality (12 miniatures)

Carefully sculpted atmospheres, a tiny sampling of a larger worlds. Each of the 12 pieces play in sequence along with photographs (Joyce Graves).

The Derelict

A curious journey; best with headphones. Derived entirely from the bowed spring reverb instrument prototype built by Jay Kreimer, Melodyne and other tools revealed metallic insect choirs, low-flying ghost airplanes and other curiosities.

Stations of Time

A project that arose from the Invisible Cities with Bryan Day and Jennifer Wilsey, a surprising tribute to radio time signal stations that used to help us tell time. It was featured on Marcelo Diaz Soto’s Radio Ambient in February 2024.

The Rain Shadow

In three movements, the expansive feeling of forces much too large to comprehend. Sculpted meticulously over the course of four months, beginning shortly after lockdown in April 2020.


Channeling the ancient Japanese practice of joining together broken pottery: six new sound sculptures from recording studio fragments, 1976-2019.

the spaces between

the spaces between is a series of 12 immersive recordings created in April 2019 while in residence at the Lucid Art Foundation (Inverness, California). They were realized in the studio of Gordon Onslow Ford, a painter who spanned numerous art movements and pioneered new concepts exploring inner worlds. Attributions for this album are here.

20th Century Tape

This body of exotic electronics emerged from reel-to-reel tapes originally recorded at a synthesizer studio in Lincoln, Nebraska from 1976 to 1980. A video of one piece performed live in 2017 (Fear of Tar) can be found here.

Emergent Frost Variations

New pieces that weren’t a part of a larger theme were drafted, intermittently revised and then finished over the course of six years: subtle sonic explorations realized using a variety of sources and methodologies.
