From a young age, Harrison was surrounded with the sounds of brass, his parents and family all being involved in brass bands. Quickly captivated, he began playing the trombone at the age of 8. Harrison’s love for the trombone grew with his love for classical music, and in the later years of high school, he began dreaming of a career in classical music and performing in one of the world’s best orchestras.
Having grown up predominantly as a soloist in his high school years, Harrison has won numerous solo state- and nation-wide competitions, including sections in the Australian National Band Championships since 2015, finalist and winner of the Australian Youth Classical Music Competition in 2021, and finalist in 3MBS The Talent in 2019. Since 2019, Harrison has been involved in frequent Australian Youth Orchestra programs and was a part of its most recent International European Tour this year, performing in some of the most famous concert halls in the world like the Musikverein in Vienna and The Concertgebouw in Amsterdam.
