The annual Glasperlenspiel Music Festival (Glass Bead Game Festival, in Estonian Klaaspärlimäng) is a joint project of Eesti Kontsert and Estonian Record Productions since 1995. It is a leading musical event in the Estonian summer.
Peeter Vähi, a composer and music producer, is the artistic director of the festival.
The Glasperlenspiel Festival is inspired by Hermann Hesse's novel The Glass Bead Game, and its content is intended to present music from unusual angles, occasionally tied to a literary, religious, philosophical, esthetical or some other theme. Recent offerings include Nietzsche contra Wagner, Mozart & Salieri, Jungle Book of Baroque, Carmina Burana Speciale, Da Vinci Code, End of the Era of Composers, Music for Glass Harmonica, and Freemasonic Music.
