3 Grounds 3 (1993) by Robert Davidson. Performed by Topology, 1997. 

One of Topology's earliest performances in early 1997. John Babbage, soprano saxophone; Christa Powell, violin; Robert Davidson, double bass; Kylie Davidson, piano.
The composer embraced counterpoint enthusiastically after spending much of 1992 studying vocal music in Kerala, India. After deep immersion in melody, an contrasting embrace of polyphony became highly attractive to Davidson.
