gone rogue, dance-wise, taking three or four classes a day from studios all over New York City -- jazz, modern, tap, salsa, flamenco, belly-dancing, break-­dancing, West African, pole dancing, capoeira -- borrowing gestures and movements and boiling them all down into her own unique B-girl bouillabaisse.

As Krupnick listened to the album, it struck him that Girl Talk makes music the way Anne Marsen makes dance. "I started to hyperventilate a little bit, the way you do when you get excited about something that you really want to come true," he told me.

Yet, in a press conference held in Cunningham's dance studio shortly before his death, Fishman announced, "The future of his life's work cannot be left to chance."

Cunningham, according to board member Allan Sperling, "wanted clarity with respect to the ownership, control, and continuity of his choreography." Mr. Sperling adds, "He wanted it to be in the hands of those he trusted to carry out his philosophy and approach." The trust, which has meticulously documented his works, controls licensing of revivals. "Presumably," Sperling says, "the trustees will set standards for the way the work is performed."

New York choreographer Jane Comfort has been inhibited artistically in the past by copyright barriers. She now commissions new scores for her dances rather than attempting to use copyrighted music. "It is stultifying and difficult," she says. "The music industry and literary estates can be really tough."

Contemporary composer Joel Durand, a professor of composition at the University of Washington in Seattle, knows composers rely on royalties for income but says, "I wish we were not so obsessively entrenched in our little discoveries." He'd like his work to be freely available since, Durand says, "Everything we do is universal in a spiritual way. It all belongs to everybody because it doesn't come from us as individuals." Works "of an aesthetic nature," he adds, are produced "in collaboration with the world, and the creator should offer it to all rather than clasp their fists around their thought for gain."

Holby, too, wonders if unfettered access might flower into "a new Renaissance with everyone inspiring everyone else."
