What is classically trained, exhilarating to behold and suspended 25 meters from the ground in Sydney at the Queen Victoria Building's iconic stained glass dome?

The remarkable musical stylings of Shenzo Gregoria.

Gregoria plays his electric violin from June 16 - June 18 while suspended from the roof of Sydney's Queen Victoria Building (QVB) as part of his latest public performance.  The QVB was designed by George McRae and completed in 1898, replacing the original Sydney markets on the site.  It is now one of Sydney's premier shopping centers.
