MYSTERIOUS EXIT (1993) for flute and 4 percussion by Howard J. Buss. The title refers to the inexplicable disappearance of the 14th Century Sinagua Indians who inhabited an area in what is now the State of Arizona. This composition was inspired by the composer's visit to the Sinagua pueblo ruins and is a musical representation of how the Sinaguan culture graced the austere and forbidding landscape of the region. The central section of the piece exhibits some of the intriguing rhythmic asymmetry found in Hopi dance songs
