Cassette label started in the 1980's by California artist Damian Bisciglia. His Agog project has many releases on this imprint. High quality packaging was one of the hallmarks of this label as was the excellent experimental recordings to be found there.
In 2003 Damian started producing CDR releases. GYR/CDR 006 was to be Minóy "Be Cool (Spazm)" but was not released due to problems with the artwork.
