Environments (stylized in all lowercase) is a series of LPs, cassettes, 8-track cartridges and CDs created by producer and sound recordist Irv Teibel (1938–2010) for Syntonic Research Inc. between 1969 and 1979. The series consists of recordings of natural sounds such as a seashore with crashing waves or a thunderstorm with falling rain, without musical accompaniment. The series helped ignite a worldwide interest in field recordings which resulted in many imitations being released throughout the 1970s, 1980s and 1990s both with, and without, music.
"environments" LPs.
The original series, distributed by Atlantic Records, comprised 11 long-playing records with a different environment on each side, for 22 total "Environments".
"Environments 1" (1969).
The initial recording in the series goes back to 1968. Working under the direction of Tony Conrad and Beverly Grant Conrad, Teibel recorded ocean waves at Coney Island for use in their feature film "Coming Attractions" (1970). Teibel immediately sensed the marketability of this material, noting its effect on improving concentration, enhancing sleep and sex, and imparting a sense of calm to the listener. Conrad, who wished to credit Walter De Maria for his prior usage of ocean recordings, was not willing to become a partner in the Syntonic Research enterprise as envisioned by Teibel, so Teibel parted ways with the "Coming Attractions" project. Subsequently, Teibel himself felt unsatisfied with his results — though his Uher stereo reel-to-reel tape recorder had faithfully captured the sounds of the surf, he felt that they were less convincing on playback. A friend of Teibel's, Louis Gerstman, had access to an IBM 360 computer, and he and Teibel played around with processing the recordings until eventually the two of them hit upon a series of manipulations (basically some rolling filtering and overdubbing) which sounded 'more real than real.'
For the second side of the LP, Teibel recorded an enclosure of birds at the Bronx Zoo aviary.
"Environments 2" (1970).
Alone among the "Environments" series, "Tintinnabulation" is not natural sounds at all but a series of computer-generated bell sounds playable at any speed from 16 ;templatestyles src="Fraction/styles.css" / ;2⁄3 to 78  rpm. The CD reissue opted for the 16 ;templatestyles src="Fraction/styles.css" / ;2⁄3 rpm speed.
Field recording with owls, crows, doves, insects, dogs and geese recorded early one morning in June 1969.
"Environments 3" (1971).
The sounds of a spontaneous gathering in Central Park, April 6, 1969, with strolling musicians, dancers, anti-war protesters, and fragments of conversations. Most of the "Environments" recordings have been imitated, but this one—a distinct time &amp; place now gone—remains unique.
A warm summer night (recorded August 1970) deep in the backwoods of Eastern Pennsylvania, surrounded by insects and the occasional distant hound.
