Here is an amazing ocarina musician on YouTube known as Heathersocarina who uploads videos of herself playing various songs on the ocarina! Her friend Lara recently did a rendition of Ballad of the Goddess on the ocarina.
There is also a wonderful cover of Zelda's Lullaby on the harp, performed by WhiteveilHarp.
