A handy guide to a confusing quartet of musical organizations, color-coded for clarity’s sake:
Other Music: Downtown Manhattan (and online/download) record store. Kind of like San Francisco’s Aquarius, just on a different ocean (othermusic.com).
Other Minds: San Francisco-based new-music promoter and organization, run by Charles Amirkhanian (otherminds.org). … Also a philosophical conundrum (see plato.stanford.edu).
Open Mind: Fine used (and new) record store in San Francisco, relocated in 2007 to Market Street from Divisidero Street (at yelp.com). … Also a Swedish vinyl resource with an emphasis on psychedelic music (openmindrecords.se).
Open Music: Many things, including (1) a foundation focused on “how new forms of visual expression on the page can lead to previously-unknown forms of musical expression” (openmusic.us); (2) a programming language and music interface (ircam.fr); (3) an open-source (i.e., community-built) music directory (musicmoz.org); (4) a Creative Commons application of communal software conventions to music publishing (magnatune.com); (5) an archive of “out-of-copyright sound recordings” (openmusicarchive.org); (6) an ensemble with a rotating membership, led by flute player Bob Downes.
