Microsoft's Xbox 20th anniversary livestream featured an incredible performance of Halo's iconic theme music by the Sydney Youth Orchestra and Kamilaroi man Paul Glass.

It was a very Australian event, and it was incredible to watch. Performed at the Royal Botanical Gardens, on Gadigal Land, and featuring the Sydney harbor and the famous Opera House in the background, it was one of the highlights of Microsoft's event.

Sydney Youth Orchestra CEO Mia Patoulios said in a statement, "Sydney Youth Orchestras and Xbox ANZ have been in talks for some time now, and it feels great to finally get the chance to work together on such a momentous occasion for the brand."
