[3] While teaching at Queens University, Bunger became very interested in the techniques and performance of prepared piano, encountering John Cage in 1967.
Cage wrote the foreword to the book, which has been repeatedly referred to by avant-garde pianists as "the classic" in the field,[1][6][7] and which was later published in Japanese by Zen-On Music Ltd. Evans performed and recorded a concert of avant garde solo piano pieces at Oberlin, including works by Cage, Henri Lazarof, Barney Childs and Charles Ives.
Using manuscript fragments and notes, Evans reconstructed Cage's 1939 incidental music for Jean Cocteau's Marriage At The Eiffel Tower.
[10][11] Evans was invited to join Nicolas Slonimsky, Dane Rudhyar and others at the April 1973 music convocation called "The Expanded Ear", which culminated in the Six-Acre Jam, a piece in which 60 musicians played at various positions among the trees on a mountain slope.
[13] Throughout the 1970s and early 1980s, Evans toured in North America and Europe in support of music by 20th century American composers.
In November 2004, Evans took part in a collaborative composition and performance work called "Raw Impressions Musical Theater #1", with eight other composers.
[19] In 1995 Evans composed and recorded the music for the two-hour opera an oratorio based on the poetic works of William Butler Yeats, Maude Gonne, and Padraic Pearse: The Rising, An Irish Allegory.
[20] In 2001, Evans wrote the music for a performance of Thorstein Veblen's The Theory of the Leisure Class to a libretto by Charles Leipart, that was presented by the National Association of Musical Theatres in New York City in 2002 and recreated as a vaudeville production produced by Stages 2006, staged at Kansas City Ballet.
[21] This musical was rewritten by the authors, retitled as "The Price of Everything" and produced during 2010 by the 6th Street Playhouse in Santa Rosa, California, directed by Nancy Prebilich.
The initial Industry Presentations of Enchanted April, directed by Annette Jolles, were produced at the Chelsea Studios in NYC in March 2010, and starred Rebecca Luker, Jill Paice, Robert Petkoff, and George Dvorsky.
