Kontski settled in the United States in 1883 and resided first in Buffalo, New York, then in Grand Rapids, Michigan and San Francisco.

His piece entitled Polish Patrol was published in Los Angeles in 1895 by The Barlett Music Co. with a portrait of the composer on the cover, and his Awaking of the Lion was very popular in 1870s California.
