The Seattle Symphony showcases three of the city's very own composers, all of whom produce remarkably different kinds of work in terms of aesthetics. MacArthur Genius Trimpin creates room-sized orchestral art installations that sometimes look like Rube Goldberg machines. You'll get a taste of that with Solo Flute, Eight Pottery Wheels and Assorted Vinyls. Andrew Stiefel’s deceptively simple and pretty Five Ways to Listen to a Mockingbird will blur the false distinction between the natural world and the metropolis. And finally, musicians will display the full range of maraca and maraca-type instruments in Leonardo Gorosito and Rafael Alberto's mesmerizing percussive piece Seeds. This concert will also give you a chance to check out Octave 9, a newly opened, state-of-the-art space that allows the symphony to completely change the acoustics of the room to suit their needs. by Rich Smith
