Recorded in the beautiful acoustics of the parish church of Hallstatt (Austria), where Gunar Letzbor was born, this personal and dramatic interpretation of Biber’s most popular work, usually referred to today as the ‘Mistery’ or ‘Rosary’ sonatas, comes back after years of absence. Gunar Letzbor makes his journey through the ‘mysteries’ or events in the life of the Virgin Mary using two different violins and accompanied by no fewer than six musicians playing kaleidoscopic combinations of harpsichord, organ, lute, archlute, two bass viols and double bass - a big continuo group which enhances and intensifies the changing moods of the cycle.

Heinrich Ignaz Franz Biber's Rosary Sonatas (or Mystery Sonatas) c. 1678 are unlike anything else in the violin literature, with scordatura, or unconventional instrument tuning, exhaustively explored in the fifteen-piece cycle, each sonata utilizing a different tuning. Each sonata represents one of the Catholic Rosary Mysteries. As the music reaches it's spiritual climax in the "Resurrection" sonata, Biber specifies the violin be played with it's two central strings crossed. Accompanying Lina Tur Bonet, an exciting younger generation violinist, is her ensemble Musica Alchemica.
