He calls his guitar work Endangered Guitar because of the extreme alterations he enacts upon his instrument’s sound and construction, resulting in a hybrid guitar/software instrument made to interactively control live sound processing. Signal To Noise called his works “…a killer tour de force of post-everything guitar damage”, All Music Guide recommended him: “…clearly one of the best experimental guitarists to come forward during the 1990s.”
His Third Eye Orchestra compositions for large ensembles and live sound processing are inspired by Miles Davis’ Bitches Brew period and Earle Brown’s approach to form. All About Jazz called the music “nothing short of breathtaking”, and “a masterpiece of musical evocation”, AvantMusicNews the orchestra’s performance at the 2015 Victoriaville Festival “a thrilling 75-minute display that combined individual virtuosity in a cohesive and fun-filled framework.”
