"I finished writing a new album about a month ago," she told the site. "At the moment I'm in and out of the studio working with [producer] Ethan Johns."
Johns ( Kings of Leon, Ryan Adams) produced Marling's Mercury-nominated "I Speak Because I Can" and 2011 effort "A Creature I Don't Know," which failed to chart in the U.S. but peaked at No. 4 on the UK albums tally.
Marling says the new set, which would be her fourth album in five years, should be released "in about six months." In the meantime, she's playing a handful of U.S. dates before heading back to London for an evening at the Royal Albert Hall.
