As a solo artist, O’Donovan has released two studio albums: In The Magic Hour (2016), a 10-song album full of the singer’s honeyed vocals mixed with gauzy, frictionless sounds and her debut solo album, Fossils (2013), a moody collection of original songs with a country lilt. In 2018, Aoife contributed an original song Are You There to the film 'What They Had', an official selection at both Sundance and Toronto Film Festivals.
O'Donovan spent the preceding decade as co-founder and front woman of the string band, Crooked Still. She is the featured vocalist on The Goat Rodeo Sessions, the Grammy-winning album by Yo-Yo Ma, Stuart Duncan, Edgar Meyer and Chris Thile and one-third of the female trio Sometymes Why. Throughout her career, O'Donovan has collaborated with artists such as Alison Krauss and jazz trumpeter Dave Douglas, and is currently a member of the house band on the radio variety show Live From Here.
