For trombone and computer-generated sounds; 1986 ; Duration ca. 15:12

Eternal Winter has been among the most widely performed of the composer's works for soloist(s) interacting with computer-generated sounds, having received over 100 performances in North America, Europe, Asia and Australia.

The title and musical qualities of the piece were suggested by a winter landscape by Sesshu Toyo, a fifteenth century Japanese painter. In Sesshu's hanging scroll, stark, geometric images of a house, mountains, windswept trees and a brook are set off in high relief against blurred images and textures. The composer has attempted to convey some of the same powerful sense of solitude, of mystery and expanse, of icy beauty but also unleashed energy, within the interwoven trombone and tape parts of this composition.

The computer part was realized on a Sun-3 system at the Eastman Computer Center by means of Csound (Vercoe) and score11 (Brinkman), the CCSS soundfile programs (Gross), linear predictor programs, and various utilities written by the composer and other staff members at the Center.

MP3 audio excerpt
This excerpt begins (somewhat abruptly) at letter E, page 5 in the score, about two and a half minutes into the piece. The excerpt is taken from a pre-release edit of John Marcellus' compact disc recording of the work. It features several of the extended techniques used in the work: lip trills, slide "glissandi" on a single note (varying the timbre rather than the pitch), singing and screaming into the instrument while also playing notes, brief melodic lines or rips, and so on.
