-description: "Music With Motion: Down Under is a dynamic celebration of Australia's video game soundtracks—performed live by a full wind orchestra and synchronised in real time with stunning visuals on the big screen. Premiering all-new orchestrations created especially for this event by award-winning Artistic Director Dr Nathan Cummins, the performance showcases music from games developed across the country, including several from right here in South Australia. Many of these games have never had their music performed live, and you'll be among the very first to hear it."
