Born and raised in small-town Motueka (New Zealand), Callum’s career began at 15 when he started gigging with his own jazz group, and participated in various festivals and competitions. His achievements include winning the Most Outstanding Jazz Guitarist and Most Outstanding Musician awards at the Southern Jam Youth Jazz Festival.

Callum completed a Bachelor of Music and a Post-Graduate Diploma in Jazz Performance at the New Zealand School of Music (NZSM), and went on to teach Jazz Theory at NZSM, jazz guitar in the Young Musician’s Program, and private guitar tutoring.

After a year in Berlin, Callum returned to NZ in 2014 where he and Jake Baxendale formed Antipodes (with pianist/composer Luke Sweeting) and The Jac.

In 2016 Callum’s Sons of Thunder (from The Jac’s 2015 album, The Green Hour) won the inaugural APRA Best Jazz Composition Award at the NZ Jazz Awards. He won it again the following year with Deep Thought from the 2018 Antipodes album, Good Winter, and in 2019 was a finalist for his piece, Chungin.

In 2017 Callum worked with Korean traditional/fusion group Black String, preforming commissions at the Wellington Opera house as one of the 2017 Wellington Jazz Festival headline acts. The ensemble went on to perform at the Bukchon Traditional Music Festival and Jarasum International Jazz Festival in Korea.
