"…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

“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
