The cost of the project so far, even in October 1966, was still only $22.9 million, less than a quarter of the final $102 million cost. However, the projected costs for the design were at this stage much more significant.
Music of Sydney
The Sydney Symphony is internationally renowned and regularly performs in the Concert Hall (2,600 seats) of the Sydney Opera House under Chief Conductor Vladimir Ashkenazy. City Recital Hall is dedicated mainly to chamber music and chamber orchestra concerts, featuring many famous international artists as well as concert series by fine local groups such as the renowned Australian Chamber Orchestra and Sydney's foremost Baroque orchestra, the Australian Brandenburg Orchestra. 
Opera Australia, the world's third-busiest opera company, has its headquarters in Sydney and performs a busy program of mainly classical and occasionally contemporary operas at the Opera Theatre of the Sydney Opera House. Sydney is the birthplace of the composer George Frederick Boyle.
