In Layerings prerecorded sounds of vibraphone and other percussion instruments are processed and mixed to create a tapestry of sonic material from which and into which the vibraphone emerges and merges during the course of the performance. I have attempted to create an integrated sequence of textures in which the vibraphone and tape parts weave through and around one another. The dynamic level is generally quiet, with the tape part functioning as both accompanist and contrapuntal partner.
Layerings was written between 1991 and 1993; it was commissioned by percussionist Beverly Johnston with financial assistance from the Canada Council. Ms. Johnston premiered the work at the Music Gallery in Toronto on March 11, 1994.
