The Washington Chorus, Washington

When the Rolling Stones wanted a chorus to sing with them during their last gig on their "50 and Counting" tour, they knew who to call: The Washington Chorus. That unexpected melding of talent is a testament to the group's stellar reputation—the Grammy-winning ensemble, lead by music director Julian Wachner, is noted for its ability to engage a wide range of audiences. And they've done just that for more than 50 seasons, delighting ears with a repertoire of classical masterpieces and modern compositions. Equally committed to enriching their community, the chorus performs free concerts throughout the greater D.C. area, sponsors a junior choir, and gently corrects anyone who misspells "requiem."
