Laura Marling’s fourth album is already shaping up to be her best yet, as this fall’s A Creature I Don’t Know tour has brought a number of live previews so far, each sounding to these ears even better than the last. “So your grandmother sounds to me,” she sings in this cutting tune to an ex about “when we were in love, if we were” from Chicago’s Lincoln Hall. “A woman I would be proud to be / And you say she reminds you of me / Every little boy is so naive.” Marling has said that she plays new material during most sets to raise the stakes by risking a mishap or two. To wit, enjoy her false start and stunning recovery in the tentatively titled “I Was An Eagle” above.
