On Saturday, Oct. 5, CBS This Morning rewarded early birds with a chance to see Lily & Madeleine making their first appearance on national network television.

Lily and Madeleine Jurkiewicz, the Indianapolis-based sister duo who were first discovered singing world-weary harmonies on YouTube, will be making the transition to morning TV as part of This Morning’s Second Cup Cafe series, for an interview and performance of two songs yet to be determined.

With their songwriting partner, bassist Kenny Childers (Gentleman Caller), Lily & Madeleine have already recorded a substantial repertoire of original material, starting earlier with this year with a five-song EP, The Weight of the Globe. That disc’s combination of heavy emotions and light, delicate arrangements had the Guardian praising their “shocking” musical talent and “mountain airĖpure” voices.

Now the countdown has begun to this month’s release of the duo’s first full-length, a self-titled disc of a dozen all-new songs. Out October 29, Lily & Madeleine finds the duo moving confidently forward from that EPóboth as a musical jumping-off point, and as a personal coming of age.
