Jeff Gburek, born 1963, is a guitarist/electronic music composer and sound sculptor working throughout Western Europe and the USA. He employs extended and prepared guitar techniques, signal processing, open source applications and field recordings to create richly textural music linked to musique concrète and electro-acoustic music, wherein extreme pianissimo, organic object manipulation and silence contrast energetic swells of electronics. For 8 years he has worked with movement artist Ephia in Djalma Primordial Science  evolving a praxis of body and sound through performance and pedagogy. Other projects include the Berlin-based electro-acoustic trio ZYGOMA with percussionist Michael Vorfeld  and sampling by Michael Walz. Appearances with Keith Rowe, Tetuzi Akiyama, Kyle Bruckmann , Pascal Battus, Raven Chacon, Tatsuya Nakatani, Annette Krebs, Lucio Capece and Tom Carter (Charalambides), show him crossing many strains of improvised, electro-acoustic and experimental music. He is known for his CD "Energariums" on the Nur Nicht Nur label  He has recently been building a unique electronic environment for processing guitar and field recordings at STEIM in Amsterdam, September 2005.
