The last time Laura Marling performed for Spinning On Air, her performance yielded a recording of “Rest In The Bed” that was brilliant enough to be chosen as the B-side to A Creature I Don’t Know single “Sophia.” Now she’s returned to WNYC’s studios for another round of LP3 previews, including “Night After Night,” the set’s Leonard Cohen-esque sixth track, which Marling unveiled via another release-ready live take. In-studio footage can be seen above.

Meanwhile, she echoed Ryan Adams’ metal appreciation recently by unleashing an Iron Maiden-shirt-donning set at the Cambridge Folk Festival.

Update: Here’s “I Was Just A Card” (both clips after jump).
