She is a Pennsylvania native from Chester County, near Philadelphia, and began singing and playing piano at a very young age; she marks the turning point in her life at age nine, when she performed an original song for the students in her elementary school and received an enthusiastic reception.

Longley began recording a demo album and performing in clubs, competitions, and local festivals while attending Downingtown West High School. Her song "Naked Trees" reached the number one spot on GarageBand.com and held it for several weeks.

Upon graduation, she won a scholarship to Berklee College of Music in Boston and studied voice. She continued writing and recording. Somewhere in the Middle, her self-released debut album, was recorded while she was still a student. She also took first place in the Rocky Mountain Folk Fest Songwriter Showcase, and was co-winner of the Mountain Stage New Song Contest.

Graduating from Berklee in 2010, Longley won three songwriting competitions: the BMI John Lennon Songwriting Scholarship Competition, the International Acoustic Music Awards, and the Chris Austin Songwriting Contest. She also recorded her sophomore effort, Hot Loose Wire, which featured two of her award-winning songs as well as a cover of Van Morrison's "Moondance," which was picked up by Sirius XM programming executives for regular rotation.

Longley's reputation spread fast and she moved between Boston and New York. She began opening shows for a wide range of artists including Shawn Colvin, Paula Cole, Nanci Griffith, and Amos Lee, and began accepting writing assignments for television and cinema. She placed songs on the ABC series NY Med and her "This Is Not the End" was showcased in the grand finale of the series Army Wives.

In 2011, Longley moved to Nashville and began collaborating with some of Music City's notable songwriting talent. She co-wrote with Amy Stroup, Phillip LaRue, Peter Groenwald, and Blake Stratton. The recorded fruit of those sessions was the six-track Inside This Song EP in late 2012.

After extensive touring and writing over the next year and a half, Longley began a Kickstarter campaign to finance her next album. Her initial goal was $35,000; she raised $55,000. She signed with Sugar Hill in 2014 and began recording at Ocean Way Studios with producer Gus Berry (Jaquire King, Charlie Worsham) and engineer Gary Paczosa, as well as a slew of first-class session players. "Bad Habit," the album's first single, was released to digital media and did exceptionally well. The self-titled album was released in March of 2015, followed by her first national headlining tour.

Longley re-entered the studio in the winter of 2016 and emerged with the full-length Weightless in August. The pre-release cut "Swing" made several streaming charts. The album also contained a re-recorded version of the track "Rescue My Heart," that was used in ABC's Switched at Birth and MTV's Scream: The TV Series. ~ Thom Jurek
