Wow, what an amazing project! I believe music should play a much bigger role in all kinds of healing processes than it has been so far - I've just recently learned about a project (and seen how it works) in which music is played to elderly people with Alzheimer's, specifically music they listened to when they were young - and just for these moments they remember all the lyrics and sing along and dance and dive into all emotions they've always connected to these songs, it's just wonderful.
