The Imperial Symphony Orchestra is an approximately 80-member coterie of melodically-minded do-gooders, largely made up of volunteer musicians, who provide high-quality entertainment. Today’s deal gets you a best-available reserved seat to all five of the orchestra’s 2010–2011 Masterworks performances, which celebrate the accomplishments of some the world’s finest, most eccentric composers. The initial, October 5 concert kicks things off by traversing the fifth symphonies and concertos of such storied composers as Beethoven, Bach, and Tchaikovsky, whose Symphony no. 5, movement II revealed that Paul was dead and John was the walrus nearly a century before it became popular knowledge. Future concerts include Respighi’s Pines of Rome and symphonized Christmas music featuring a kinetic kick from members of Florida Dance Theatre.
