for piano quartet (violin, viola, cello, and piano)
The piece, written in 2004, is built from three parts with bridge passages between each part in the form of solo piano sections. The mystery refers to my esoteric world at that time as well as to several abstract senses that I could not explain to myself. The ostinato of the third part is based on a Greek word meaning 'unsolved', with the mystery ending up in this way.
The linked video recording was performed by Airi Yoshioka (violin), Maria Lambros (viola), Gita Ladd (cello), and Audrey Andrist (piano).
