PGR started life as an industrial group in mid '80s under the Poison Gas Research moniker. Their studio was in a rough area in Oakland. To deter dubious people they affixed a sign with "Poison Gas Research" written on it at the front door. After self publishing several cassettes under this name, the group name was shortened to PGR. Their first LP was Silence, which inspired the name of PGR mainstay Kim Cascone's label (and later distribution company) Silent. On this label a series of LPs and CDs was released, among them 'The Black Field' and 'The Chemical Bride'. In addition to these, a double CD was released to celebrate the 50th anniversary of LSD titled '50 Years Of Sunshine' (a collection with Genesis P-Orridge, Hawkwind and Timothy Leary). Over the years, the music of PGR navigates through industrial, psychedelic, ambient and musique concrète. <a href="https://www.last.fm/music/Poison+Gas+Research">Read more on Last.fm</a>.
