Balthazar Mattar is a London-based artist. He has presented three solo exhibitions in London and participated in art fairs across the UK, Germany and Denmark.

Originally a musician, Mattar studied Classical Composition at King's College London from 2010 to 2013. After graduating, he spent over a decade performing, writing and recording with experimental and post-punk projects, including Hi-iD and Glass Disguise, becoming an active presence within London's leftfield music scene.

Throughout this period, visual art remained a parallel pursuit, but it was not until the beginning of the pandemic in 2020 that he committed to the practice full-time. Over the following years, he developed a distinctive graphic language using vintage typewriters and emulsion paint. This culminated in a body of work titled Object Art, which was exhibited across three London solo exhibitions and achieved considerable commercial success.

In 2025, feeling he had reached the limits of that visual language, Balthazar shifted his practice in a new direction. Through self-directed study of draftsmanship techniques, and regular life drawing classes at the Royal Drawing School, he developed a more figurative approach. His current work explores the relationship between humanity's primordial drives and the artificial environments it constructs around itself, examining the tension between instinct and artifice
