Our High Schools Orchestra was formed in 1975 and is the largest high school aged ensemble in the music service.
The orchestra has toured the USA , Malta and most other countries in Western Europe. It performs in prestigious venues across Cardiff and has also performed at Music For Youth venues, such as the Royal Albert Hall.
