Viewed by many as a next-generation version of Gillian Welch, Jarosz signed a deal with Sugar Hill Records when she was just 16. A debut album, Song Up in Her Head, appeared from the label in 2009 and quickly garnered tremendous critical acclaim. That same year, Jarosz began work on a major in contemporary voice improvisation at the New England Conservatory of Music, proving once again that she was no garden-variety musician. A second album, Follow Me Down, appeared from Sugar Hill in the spring of 2011. Jarosz recorded her third album, Build Me Up from Bones during her final semester in school. It contained nine originals and a pair of covers: Bob Dylan's "A Simple Twist of Fate" and Joanna Newsom's "Book of Right-On." The set was issued by Sugar Hill in September of 2013.
After extensive international touring, she was selected by Garrison Keillor to act as an occasional guest host for A Prairie Home Companion radio program. Jarosz relocated to New York City. That transition was readily reflected in her new work. She reentered the studio in 2015 with co-producer Gary Paczosa. Playing guitar, octave mandolin, and banjo, she was accompanied by Jedd Hughes, Luke Reynolds, and Mark Shatz. Sara Watkins and Aoife O'Donovan (her bandmates in the trio I'm with Her) appeared on the track "Still Life." Undercurrent was released in June 2016 by Sugar Hill. Later that summer, Jarosz and O'Donovan were named to the newly formed house band for A Prairie Home Companion under host Chris Thile, who took over for Keillor in October. ~ Steve Leggett, Rovi
