Em Glasser

Artist, Songwriter

Growing up on the shores of Miami Beach, Em’s music echoes the nostalgia of her youth, heavily influenced by the ocean and the Miami scenery. Discovering her passion at the age of 14, and signed by Majestic Casual at only the age of 17, she released her self-produced debut EP ‘April’. Now based between Paris and Berlin, she infuses her experiences of these cities into her sound. Her song ‘Strawberry Picking’, which has reached over 1 million is only the beginning to this rising artists success.
