When he was just eight years old, he started playing the trumpet, urged on by a primary school teacher. As a young musician, he was involved in various Cambridgeshire Music events and activities, including some work with its ensembles in the early 2000s. “It was a really important experience because it set me up to understand what it’s like to play with others,” Jackson remembers. “You have to get used to that. There’s only so much you can do in a practice room by yourself.”
