Bill Horvitz stretches the boundaries of guitar music and points it in new and exciting directions. Horvitz fuses traditional and extended techniques in a most inventive way; his strikingly personal instrumental vision endows the music with an infinite array of tonal color. His long and varied experience in the realms of jazz, rock, classical, folk, and new music have resulted in an entirely original compositional voicea voice that is forceful and innovative, yet always intelligently accessible. Since 1974, Horvitz has led both large and small ensembles. Between 1978 and 1988, he lived and worked in New York City, where he explored and extended the sonic range of the guitar in a wide variety of settings. While in NYC, he led the quartet Living With Apparitions and was a member of the band The Public Servants. He has collaborated with many musicians and composers, notably J.A. Deane, Joseph Sabella, Butch Morris, Elliott Sharp, John Zorn, Bobby Previte, Shelley Hirsch, Denman Maroney, Herb Robertson, Roy Campbell, Richard Dworkin, David Hofstra, Harris Eisenstadt, Steve Adams, Sara Schoenbeck, Scott Walton, Tom Hayashi, George Cartwright, Phillip Johnston, Myra Melford, George Lewis, Bill Laswell, Dave Sewelson, Eugene Chadbourne, Frank London, and Walter Thompson.
Between 1995 and 2007 he led the Bill Horvitz Band featuring Steve Adams on woodwinds and first, Joseph Sabella and second, Harris Eisenstadt on drums. The band recorded two CDs Dust Devil and The Disappearance. He has also worked with the improvising quartet Out by Five with Jon Raskin, George Cremaschi, and Garth Powell , the Harris Eisenstadt Ahimsa Orchestra, and Moe Staino's Moekestra! In 2004 he recorded the CD Tuolumne Songs, compositions for solo acoustic guitar.
