If you understand the differences between absolute and program music and can deliver a dissertation on Baroque, Classical, and Renaissance styles then good for you. Drop me an email because some of it is completely over my head and skip this review because it's not for you.
If your looking for something different, a brief respite to rip you away from the grind and let your mind wander formlessly amid the music then check out the symphony. Despite popular belief there is no formal dress code however you might find a favorable response from your fellow patrons if you wear a shirt and shoes after all this is the symphony not the South. Though some people wear jeans you may feel more comfortable in a pair of slacks or casual business attire but ultimately who cares you paid for a ticket just like everyone else. Largely, the only complaint I can muster are the somewhat cramped seats in Phoenix Symphony Hall. Intermissions usually offer a coffee and cocktail bars. Also make sure and arrive slightly early, while they might not care about how you're dressed, etc. I promise you they absolutely will not let you to the hall after the doors close, you will be stuck in the lobby until the intermission.
Downtown Phoenix and the other symphony venues also offer a variety of wonderful places to dine before or after the performance. The Phoenix Symphony website www.phoenixsymphony.org offers additional information, performance calendars, and ticket sales. Unplug and give it a try.
