Gary has had a long career at Oberlin Conservatory of Music where he was a Professor of Electronic and Computer Music. On August 9 he will giving a talk at Entropy Gallery discussing his many years of work in the field of electronic and computer music.

Nelson is internationally recognized in his field. He has worked at Bell Laboratories, the Swedish Radio Electronic Music Studios in Stockholm and at the Institute for Research and Coordination of Acoustics and Music (IRCAM) in Paris. He has been composer in residence and guest researcher at the University of Melbourne, Australia, Taiwan's National Chiao Tung and Soochow Universities, Hong Kong Baptist University, the National Unitersity of Singapore, Moscow Conservatory of Music and Yunan State University in the Peoples Republic of China. In the fall of 1990 he spent four months in Europe lecturing and performing at universities in England, Scotland, and Holland.

Nelson has taught at summer music camps since the early 1960's. These include the Allegheny Music Festival, the New England Music Camp, and the National Music Camp (NMC) at Interlochen. At Interlochen Nelson was chair of the composition department. He also founded the NMC Computer Music Studio and established the NMC High School Synthesizer Ensemble. In the summer of 1991, he traveled to the Republic of China. In ROC, he led intensive workshops in computer music. These workshops included high school and college composers as well as teachers and other professional musicians.Nelson's computer music specialties include real time interactive performance and "hyperinstruments." This term was coined to give focus to a new way that music is being made in the early 21st century. A hyperinstrument consists of a computer, a set of digital synthesizers, a performance interface, and software for linking them all together. Nelson chooses the MIDI Horn for his solo performances. The MIDI Horn is a digital wind instrument designed and constructed at Oberlin by music engineer, John Talbert. A Macintosh computer, and an array of synthesizers from Yamaha, Roland, and E-mu Systems complete Nelson's concert setup. He has performed more than 200 times around the world since 1987.
