Despite being just 22 years old, Miley Cyrus has been a long-time and vocal proponent of helping homeless youth. She brought homeless teen Jesse Helt as her plus one to last year’s MTV Video Music Awards and had him accept her award for Video of the Year to give a voice and face to the millions of runaways and homeless youth living in the U.S.

To further support the cause, Cyrus recently launched her own Happy Hippie Foundation, a non-profit that seeks to serve “homeless youth, L.G.B.T. youth and other vulnerable populations.” To help bring awareness to her new charity, the singer has been working with a variety of musicians on new installments of her Backyard Sessions. The latest is with rock icon—and recent Rock and Roll Hall of Fame inductee—Joan Jett, along with Laura Jane Grace, the lead singer of the band Against Me!, whose own transgender journey of discovery was documented in the AOL series True Trans.

The trio teamed up for a folk-inflected cover of The Replacements’ ode to breaking down gender norms, “Androgynous.” The song, with its call for “unisex evolution” is a good fit for Cyrus, who recently told TIME that she doesn’t label herself as gay, bisexual or straight. “I’m not hiding my sexuality. For me, I don’t want to label myself as anything,” she said. “We love putting people in categories, but what I like sexually isn’t going to label me as a person.”

Cyrus and Jett previously collaborated on Jett’s track “Different” for the Backyard Sessions; upcoming releases include duets with Ariana Grande and Melanie Safka.
