A photo that Mandolin virtuoso, Sierra Hull put on her Facebook page to show her work in the studio on her 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.

Hull has played high-level bluegrass for the last 10 years—and she only turned 21 last fall. At 11, she debuted at the Grand Ole Opry, the bluegrass equivalent of a Bat Mitzvah; by 13, she’d signed with Rounder records.

Since then, Hull has kept busy, recording a pair of albums for Rounder, playing mandolin for the likes of bluegrass legend Del McCoury and ceaselessly touring.

Watch Hull make her Grand Ole Opry debut with Allison Krauss & Union Station:
