In 1979, Adams became the New Music Adviser for the San Francisco Symphony and created the symphony's New and Unusual Music concerts. A commission from the symphony resulted in Adams' large, three-movement choral symphony "Harmonium" (1980–81) setting texts by John Donne and Emily Dickinson. He followed this up with the three-movement, orchestral piece (without strings), "Grand Pianola Music" (1982). That summer, he wrote the score for "Matter of Heart", a documentary about psychoanalyst Carl Jung, a score he later derided as being "of stunning mediocrity". In the winter of 1982–83, Adams worked on the purely-electronic score for "Available Light", a dance choreographed by Lucinda Childs with sets by Frank Gehry. Without dance, the electronic piece alone is called "Light Over Water".
