Born and bred in Cornwall, Callum's musical journey began as a young lad with his dad teaching him the basics, which then led to embarking on formal instruction at age eight. During his time at Bodmin College, he served as the drummer for the college jazz orchestra, partaking in international tours to destinations such as New York and Paris. Callum pursued studies in music at both Bodmin College and Truro College before obtaining his degree in Professional Musicianship from BIMM Bristol in 2019. Callum maintains an active performance schedule as the drummer for Bailey Tomkinson and the locals, performing at various gigs and festivals across the UK.
