Audio Collage of electronic and concrete sounds.A first version of the work was completed in 1985 at Lehman College of the City University of New York, in the electronic music studio designed by the composer.Assisted by students, he used mostly analog equipment. For the final version completed in 2013, the first version was digitized, revised, andre-mixed at the Computer Music Center of Columbia University. The aim was to incorporate sounds and audio events the composer has experiencedfrom his arrival in New York City in 1969 up to the time of the work's completion.Close to the end, he is heard at the piano in a short jazzy episode. The prolonged electronic opening and concluding sonorities, as well as the rhythmically varied ones that are heard throughout the piece, are meant to frame and hold together the disparate concrete city sounds, some of which are themselves electronically produced. Esthetically, the overlapping and interaction of various musical idioms that tendto harmonize toward the end (including an orchestral tuning) suggest how far whatis regularly considered as music can be experienced as sound-environment, andvice versa. G. C. The work is available -- In a Stereo version: as a two-track audio file or a CD playable on a regular sound system -- As a four-track audio file, playable from a computer using an audio-sequencer software, connected through an audio interface to four loudspeakers
