The Longwood Symphony Orchestra brings its unique blend of music and medicine from Boston for its first international "Healing Art of Music" tour, focusing on the care and treatment of patients with cancer. The concerts will raise funds for the new support centre at Barts for patients with cancer and for Marie Curie Cancer Care.
I've long been a fan of music therapy - using the power of music to enhance healing and wellness. There are lots of references in the Wikipedia article if you'd like to learn more. Also check out the Longwood SO's Healing Art of Music blog.
