Demers is concerned about the fate of transformative appropriation—the creative process by which artists and composers borrow from, and respond to, other musical works. In the United States, only two elements of music are eligible for copyright protection: the master recording and the composition (lyrics and melody) itself. Harmony, rhythm, timbre, and other qualities that make a piece distinctive are virtually unregulated. This two-tiered system had long facilitated transformative appropriation while prohibiting blatant forms of theft. The advent of digital file sharing and the specter of global piracy changed everything, says Demers. Now, record labels and publishers are broadening the scope of IP “infringement” to include allusive borrowing in all forms: sampling, celebrity impersonation—even Girl Scout campfire sing-alongs.

Paying exorbitant licensing fees or risking even harsher penalties for unauthorized borrowing have become the only options for some musicians. Others, however, creatively sidestep not only the law but also the very infrastructure of the music industry. Moving easily between techno and classical, between corporate boardrooms and basement recording studios, Demers gives us new ways to look at the tension between IP law, musical meaning and appropriation, and artistic freedom.
