The Baha'i Writings speak of music as being "the ladder of the soul".
This video, spotted on Tralalere! (linked at the right) is the most concrete example of this belief that I have ever seen.
Alice, who turns 107 this month, is the oldest Holocaust survivor. As you will see, it is literally music that saved her life.
I hope that you enjoy the trailer - I can't wait to see the feature length!
