The video below is a lovely feast of rich sounds. From their website:

The stage is our canvas, our voices are our colours. We blend and unite them to create masterpieces. Happy faces give us energy and confirm that we are devoted to what we do with our hearts and souls.Perpetuum Jazzile is Slovenia’s only jazz choir, conducted Tomaž Kozlevčar who is also its art director. It thrills its audience with a colourful programme, extraordinary singing and unique joy.

Watch it with the children a few times throughout the day. Music appreciation? You bet!
