Have you ever heard music played on glass instruments before? The creative minds behind tonight's innovative concert, City of Water, Sea of Glass, say composing music for instruments that did not exist yet was an exciting and challenging experience.

Benton Roark, one of five composers involved in the project, says the process of composing music for the concert was particularly challenging because he had to imagine what the instrument would sound like. At that point, the designers and sculptors had not made the one-of-a-kind instruments yet.

The Rainbow, a series of colourful glass bowls that will be filled with water for the performance, was designed by sculptor Robert Studer, who says he drew inspiration from his travels in Southeast Asia.

Redshift Music Society is hosting tonight's sold out concert at The Waterfall Building on West 2nd Ave in Vancouver. The Fringe Percussion Quartet will perform on original instruments, premiering locally-composed music.

The evening will culminate in a performance of Water Music by Chinese composer Tan Dun, who also wrote the score for Crouching Tiger, Hidden Dragon and the 2008 Beijing Olympics.
