In 1984, Neill completed Orbs, his first significant composition for mutantrumpet, percussion, and audiovisual projections; those include 1985's Mainspring, 1987's Money Talk, and 1988's Abblasen House followed prior to his popular work In the Shadow of Forward Motion in a 1989 collaboration with visual artistDavid Wojnarowicz. in 1985 he travelled to Amsterdam's Steim Studios to develop a new, MIDI-capable mutantrumpet; the upgrade resulted in the advances in the number of switches, knobs, and pressure-sensitive pads allowing the player to trigger and modify a variety of sounds and sequences, as well as lights and projections. After Haydn, a collaboration with electronic composer Nicolas Collins, followed in 1991. Neill then began a six-year job as a pro-former of the N.Y.C. performance space The Kitchen, a position which served to spark his interest into the burgeoning electronic music scene. Neill then began increasingly incorporating electronic influences into his work. In 1996, Neill contributed to the AIDS benefit album , produced by the Red Hot Organization. In 1999, he was included in the Wired magazine compilation Music Futurists. Neill spent seven years as the music curator for The Kitchen in New York. He has collaborated with DJ Spooky, David Wojnarowicz, Page Hamilton, Mimi Goese and Nicolas Collins, and performed on albums by David Behrman, John Cale and Rhys Chatham. His music has been recorded on the Universal/Verve, Astralwerks, Thirsty Ear, Six Degrees, Ramseur, New Tone and Ear-Rational labels. Neill invented the mutantrumpet, a trumpet equipped with extra bells and valves as well as electrical modifications that allow him to control computer variables with his playing. The first mutantrumpet had three bells, six valves, a trombone slide and an analog processing system. At the STEIM Studios in Amsterdam, he developed a MIDI-capable mutantrumpet, which contained more switches, knobs and pressure-sensitive pads so as to allow greater control over the sound and visuals of his sound installations. Robert Moog designed its original electronic processing system and David Behrman designed a computer program to facilitate live performance. In 2008, Neill completed a new version of his instrument during another residency at STEIM. In 2014, he returned to Amsterdam to design another version. In 2010, his music theater work Persephone, a collaboration with Mimi Goese, Warren Leight and Ridge Theater featuring Julia Stiles, was presented at the Brooklyn Academy of Music's Next Wave Festival. The music from the production was released as a CD as Songs for Persephone on Ramseur Records in 2011. The Demo, an electronic opera co-created with composer Mikel Rouse and based on Douglas Engelbart's 1968 demonstration of early computer technology, was premiered in 2015 at the Bing Concert Hall at Stanford University. Neill has performed his music extensively in a wide variety of international settings including the NIME conference and Cité de la Musique in France, the Berlin Love Parade in Germany, the Festival dei Due Mondi and Umbria Jazz Festival in Italy, the Bang on a Can festival in New York, the Istanbul Jazz Festival in Turkey, and the Institute of Contemporary Arts and Edinburgh Festival in the UK. The Sci-Fi Lounge, his collaboration with DJ Spooky and Emergency Broadcast Network, toured America and Europe in 1997. His 2002 album Automotive was an early example of the convergence of content and commerce; the album is composed entirely of extended versions of music he originally wrote for Volkswagen TV and Internet commercials. Neill collaborated with visual artist Bill Jones to create Palladio, an interactive movie based on Jonathan Dee’s 2002 novel of the same name. Palladio premiered in 2005 at the New Territories Festival in Glasgow, Scotland, and at the Leonard Nimoy Thalia at Symphony Space in New York City. Neill is also active as a sound and installation artist. His collaborative works with Bill Jones have been exhibited in museums and galleries including Exit Art, the American Museum of Natural History and the Sandra Gering Gallery in New York, and the Wellcome Gallery in London. Neill’s installation/performance "Green Machine" was shown at the Paula Cooper Gallery in 1994. In the Shadow of Forward Motion, his major collaborative piece with the late artist David Wojnarowicz, has been exhibited in venues such as the New Museum and PPOW Gallery in New York. It was featured in the PBS documentary Imagining America. He began his teaching career in 2007 as a professor of music technology at the New Jersey Institute of Technology. As of 2017, he is currently a professor of music industry and production at Ramapo College, also in New Jersey.
