While I’m still looking forward to hearing her go electric in the studio, the first non-live preview of Lisa Hannigan’s forthcoming (9/20) sophomore LP, Passenger, offers a more settled transition between her debut and the new set. “A Sail” showcases Hannigan’s most effortless talent: indelible melodies sweetly sung with just the right melange of nuance and dramatic undercurrent to honor the tune’s muse. Here’s hoping the bluesy, brooding new jam “Flowers” will be the first single, but for now, listen above to this promising preview.
