The close of the week offers a chance to join the Olympia Symphony Orchestra and guest pianist Wolfgang Wortberg for "By Audience Request," a performance promising Beethoven's Piano Concerto No. 1 in C major, Op. 15, Verdi's Overture to NabuccoI, Grainger's Irish Tune from County Derry and Stravinsky's Suite from The Firebird. While the Olympia Symphony Orchestra rarely-if-ever disappoints, much of the pre-show hype for this events centers on Wortberg's piano skills, and rightly so. As the Symphony's website notes, "Known for his musical insight, beautiful tone, and technical command, pianist Wolfgang Wortberg has performed in venues across the United States and Europe.  Audiences and critics alike acclaim his unique concerts: portraits of a single composer, interweaving music with insightful reflections on the life and work of the composers themselves and their contemporaries."

Catching Wortberg and the Olympia Symphony Orchestra as a Sunday nightcap seems like a sure bet for good times and ageless music. But you're advised to test that statement for yourself.
