O'Donovan grew up in Newton, Massachusetts. Her parents were both musicians, and her father was the host of a Celtic music program in Boston. While in high school, she spent her summers studying traditional Celtic music and dance in Ireland. O'Donovan attended the New England Conservatory of Music and graduated in 2003. While there she studied contemporary improvisation. She also dreamed of recording her own album, and came up with a short list of producers.
Meanwhile, after five studio offerings and a live album, along with international touring, Crooked Still went on an extended -- though reportedly temporary -- hiatus in 2011 so the bandmembers could pursue individual projects. During the group's break, O'Donovan made good on her dream: she signed to Yep-Roc and cut her debut album, Fossils, with Tucker Martine as producer -- he was at the top of her college short list. The record was issued in June of 2013. O'Donovan toured relentlessly in support of the recording, headlining club gigs and playing music festivals internationally, and also assisted on the New York chamber's ensemble Brooklyn Rider's Almanac album.
After the death of her 93-year-old grandfather, she experienced ten days of solitude, during which she worked on editing and writing new songs. In early 2015, she entered Martine's studio in Portland, Oregon, to begin working on her sophomore album. Much of her new material had yet to be performed. Over three marathon sessions, the pair built the recording from the ground up; they enlisted contributions from Jarosz, Sara Watkins, Gabriel Kahane, Thile, and Brooklyn Rider. Entitled In the Magic Hour, it was released in January of 2016. That summer, she and Jarosz were named to the newly formed house band for A Prairie Home Companion under Thile, who took over hosting duties for the retiring Garrison Keillor in October. ~ Thom Jurek
