The Thai Elephant Orchestra

I can't remember where I initially came across this story. In an elephant sanctuary in Thailand, a neuroscientist and composer named David Sulzer (in his musical work he uses the name Dave Soldier) has taken the time to create musical instruments sized specifically for elephants, and teach them how to play them.  He claims to have been inspired by seeing elephants appreciate the singing of their mahouts as well as other music they came across.
 
You can listen to the NPR story about the elephants here

The official website of the sanctuary is here. (It's apparently a big tourist draw)

You can find recordings of the Thai Elephant Orchestra here (They are also available on Amazon and other music sellers)
