Lo-fi live performance recording circa 1992, at the Perel Gallery in Vancouver. In the first half of the piece, four volunteer performers are given envelopes containing photographs they've never before seen. The envelopes are opened and the four performers simultaneously describe details of each photograph in turn. While they are doing this, my software tracks the pitch and volume contours of their voices and stores the data. When the performers have described all their photographs, they sit down and the recorded data is used as score material for sounds deployed in the second half of the piece. Performers on this occasion were (I think) Ann Hepper, Michael O'Neill, Greg Higgs and Sam Salmon.

This is a piece I keep meaning to go back and revive using SuperCollider. This version was done, I think, using HMSL (Hierarchical Music Specification Language), by Phil Burk.


released January 1, 1992
