As a singer, arranger, composer, producer and multi-instrumentalist, it should come as no surprise that Jacob Collier comes from a profoundly musical family. His maternal grandparents were both professional violinists, his mother is an accomplished violinist and longtime instructor at the Royal Academy of Music in London and so, naturally, Collier taught himself to play every instrument he could find.
