Steina Vasulka - Vocalisations (1990) - Projected Video Environment. "There is an integration of sound and image in which the singing voice of Joan La Barbara produces energetic permutations in a grid of lines reminiscent of the musical staff of traditional music notation, forming a window onto images of a moving landscape. The rifts, chants, and scat singing of La Barbara�s voice become a visual dance in this electronic scape."
