Instilled from an early age with a love of Jewish music by his father Rev. Herschel Caplan, and encouraged by leading chazzan, Asher Hainovitz, Moshe developed a pure tenor voice that is at once lyrical and powerful.
He has acted as chazzan in communities across the UK, as well as in South Africa and Israel, leading Shabbat and Yomtov services. He has been very involved with the renowned Shabbaton Choir and performs at chuppahs and batmitzvahs nationwide.
