Luluc hails from Melbourne, Australia, but the duo has new roots in Brooklyn, NY, where its second album, Passerby, recorded by The National's Aaron Dessner, originated. Passerby is gorgeous and deceptively simple, boasting crisp folk songs full of melody and heart. The band's generally timeless sound is airy and accessible; fans of English bands from the '60s like Fairport Convention should feel comfortable with Luluc, as will those who dig on newer artists like Bon Iver or Alela Diane. It's quiet but not quaint, mellow but not monotonous. Let Luluc ease your eardrums into Thursday's show; though headliner J. Mascis, of Dinosaur Jr., has challenged the structural integrity of the 40 Watt with the loudness of past shows, his newest album, Tied to a Star, takes a quieter, more pastoral approach.
