In April 2013, the sisters had a show-stopping performance of “Ho Hey” by The Lumineers on Nashville. When ABC released the cover to the radio, it not only became the #1 most added song in the nation, but it also rose to the Top 40 of the Billboard Songs chart. Their rendition remains the #1 most downloaded song of all the hit TV show’s releases. In addition, Maisy and Lennon have sold more singles than any other cast member on the show.
In June 2017, Maisy recorded and starred in a music video for the song "Riding Free", which is the theme song for the DreamWorks’ series Spirit Riding Free. She also played the voice of Hester in Season 3, Episode 1 of Spirit Riding Free. The episode premiered on Netflix in November 2017. Maisy also made a television appearance as a guest judge on Top Chef Jr. in December of 2017.
