Kostia, birth name Konstantin Efirmov, is a new age pianist and composer born in St. Petersburg, Russia. A gift from his parents, a 1937 Wolkenhauer upright piano, sparked his interest in music. He is formally trained in the Rimsky/Korsakov Conservatory. After completing his training he performed in Eastern Europe and Scandinavia before moving to the United States in the late 1980's. In this period he signed on with the Narada label and produced solo releases such as Suite St. Petersburg: A Piano Portrait in 1994 and 10 Pebbles in 1996.
