Keystone begins with driving rhythms that build in intensity to a luscious violin solo. After the beautiful solo is completed, a full ensemble section is presented. What makes Keystone special is how the piece intertwines the two ideas in an incredibly spectacular fashion. For more advanced groups with a strong concertmaster, this piece again proves why Alan Lee Silva is one of the top composers of string music today.
