Experimental Intermedia Foundation, founded in 1968 by Elaine Summers, has been presenting performances since 1973. Produced and curated by composer Phill Niblock, over 1000 concerts have been given at his loft, and he has opened his doors to hundreds of composers, giving them a place to explore the use of new ideas and technologies in their music.
As an offshoot of Experimental Intermedia, XI Records was formed in 1990 XI's main purpose has been to ensure that the music of composers who have produced great work over a long period of time is archived. While continuing with this goal in mind, XI is also in the process of releasing a series of compact discs by younger composers whose works have yet to be adequately documented on recordings.
