Though I've not heard Yanni before, I discovered his music by chance. And this piece called 'World Dance' reminded me of our own Retro music from Bollywood.
It's rare to hear real orchestras with so many original musical instruments being played nowadays. I remember as a child when we used to have programmes in our colony during Diwali / Ganapati festival. I used to love the orchestras especially. These days we are only subjected to electronic music! Enjoy the music. You can also catch 'Yanni-The Rainmaker' on UTube, which is also melodious plus catchy!
