This has got to be one of the most improbable, altruistic, and quixotic box sets ever produced, as it compiles 12 albums worth of almost entirely unreleased material from Oliveros' fertile early years.  That, of course, means: 1.) none of her early masterpieces like "Bye Bye Butterfly" are here, and 2.) nothing at all is included from the wildly different (and superior) work that she has done over the last four decades.  Those caveats, coupled with the inarguable fact that no artist on earth has a dozen killer albums worth of vault material lying around, makes this a pretty undesirable prospect for the merely curious or for anyone looking for a definitive retrospective.  For serious fans of early electronic music, however, this is an absolute goldmine.
