Autumn is also a country/folk singer-songwriter. In 2011, together with fellow Composer and Guitarist, Jeff Marshall, she released the album No Romeo under the name Autumn Lee. She followed that up with her second album, Angel Made of Steel, as well as the single, Invisible.

Aside from performing, Autumn has a passion for helping empower other women. In 2015 she founded the Hollywood Women's Collective, a "women's community dedicated to supporting women creatives and engendering a spirit of support, collaboration, and giving back."

During the 2017 US presidential election, Autumn lent her voice in support of her former fellow Radio City Rockettes Dancers. At the time, Trump's derogatory comments about women in the leaked Access Hollywood tape were a hot topic and the Rockettes were said to be being pressured to perform at the inauguration event under threat of financial penalty or firing, despite several being upset at what would be a tantamount endorsement of Trump's treatment of women. Despite Trump's more recent questioning of the tape's veracity , Billy Bush, then host of Access Hollywood, declared that it was indeed genuine.
