Imagine a 35-piece orchestra with strings, brass, percussion and a choir performing not classical music but a rock ‘n’ roll repertoire with renditions of hits by rock luminaries such as The Beatles, Led Zeppelin, Pink Floyd, Stevie Wonder and The Smashing Pumpkins among others. Fortunately no imagination is necessary as The Seattle Rock Orchestra (SRO) will bring its unique orchestral interpretations of rock music to Vashon at 7 p.m. this Saturday.

Billed by Vashon Allied Arts and the Open Space for Arts & Community as one of the largest single concerts in island history,  the evening will include guest appearances by Ian Moore, V. Contreras and Zack Davidson and will also showcase two Vashon youth ensembles, i Solisti di Vashon and the Vashon Youth String Orchestra.

Since 2008 SRO has captivated audiences throughout the Northwest. Recent milestones for the Seattle group include selling out the Moore Theatre, playing to enthusiastic crowds at the 2010 and 2011 Sasquatch Music Festival and contributing strings on Macklemore and Ryan Lewis’ Grammy-winning album “The Heist.”

“This will be a rockin’ event for the entire family,” said Stephen Jeong, VAA’s director of performing arts. “Parents and grandparents will relive the classic rock days and share this music with their children. The collaboration between SRO and our aspiring young musicians will be the icing on the cake, giving participants an amazing memory and inspiring others to follow their passions.”

Seattle Rock Orchestra will play at 7 p.m. Saturday at the Open Space for Arts & Community.

Tickets are $12 for students, $20 general audience and free admission for children age 8 and under. They are available online at www.vashonalliedarts.org.
