“…a connoisseur of creative perversity”

The Wire

"…a killer tour de force of post everything guitar damage."

Larry Nai / Signal To Noise

"The cream of New York avant scene delivered the musical goods in a thrilling 75-minute display that combined individual virtuosity in a cohesive and fun-filled framework."

Irwin Block / Avant Music News about Third Eye Orchestra


Live Sound Processing

Projects using the Endangered Guitar software for electronic sound processing on percussion, string and wind instruments.


Die Schrauber

With veteran circuit bender Joker Nies (Cologne), Mario deVega (Berlin) on amplified objects and turntables, and Hans Tammen (New York) on Endangered Guitar.


Iron Foundry

Tightly woven rhythms and sonic dissonances of a “low string quartet” (violas, cello and contrabass) plus percussion mix with the alien world of bizarre textures emerging from the electronic live sound processing.


Third Eye Electric Band

Dark, sometimes brooding ensemble passages mix and mingle with tightly woven drum-loops, and extended solo cadenzas build up to a mighty hymn to machine work, music of a metallic nightmare.



Dark Circuits and Third Eye, at colleges, festivals and more.


Curated Events

Dark Circuits Festival and Spectrum Series, surround sound and visual art exhibitions, and more.

Innenleben einer Maschine


Choking Disklavier, LEMUR GuitarBot, and more.


Multichannel Works

For quad, modified 5.1 Surround Systems, up to Wavefield Synthesis.

“A bracing sequence of seismic dynamics, barbarous stabs of modified frequencies, snippets taken from heaven-knows-what-third-world-radio, children at play with their own atomization, ominous manipulations…, problematic timbral layerings, rhythms that would not remain in place if nailed with a mallet.”

Massimo Ricci / Touching Extremes about Die Schrauber
