Mandolin wunderkind Sierra Hull at work on third album

Though Sierra Hull's essay-writing days are behind her—she just graduated from the renowned Berklee College of Music last May—her songwriting ones aren't. According to her Facebook page, Hull is back in the studio to record a follow-up to 2011's "Daybreak." Though details are scarce, Hull uploaded this photo of the recording space she and her Highway 111 band are holing up in.
