From the beginning, the Lily & Madeleine's calling card has been the breathtaking and intuitive union of their voices. When the two come together in ecstatic and seamless blood harmony, it's a sound that continues to haunt long after the songs are sung, leaving an electrical charge behind like a sparkling tracer in the air. When they step out individually as vocalists, Lily's warm, smoky alto is the counterpoint to Madeleine's crystalline, bell-like soprano.
