Lily & Madeleine’s goal is to release an album-a-year for three years — a rare feat when the trend among singer-songwriters is to space albums by half-decades. So far, they’re on track: Fumes, the duo’s second LP, was released October 28, 2014, 366 days after last year’s Lily & Madeleine.The sophomore album is a leap forward for the duo, a mature sentiment of two gifted young artists who have launched from their hometown onto the world stage with speed and grace. 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. Lily & Madeleine however, are equally distinctive as soloists as they are as harmony singers. When they step out individually as vocalists, Lily’s warm, smoky alto is the counterpoint to Madeleine’s crystalline, bell-like soprano. “Their voices can pierce through the chaos of everyday life and actually make you stop what you’re doing.” American Songwriter
