A transgender singer named Charlie Peck has recorded a beautiful tribute for the transgender community: a duet with himself featuring his higher register before beginning hormone replacement therapy (HRT) and with his lower register, recorded nine months into HRT.

Peck told The Huffington Post that he decided to make the video, which features a cover of “Home” by Edward Sharpe and the Magnetic Zeros, after watching other people’s voice comparison videos online ― and after thinking about how much of his identity is presented through his voice.

“I was first and foremost hoping for a voice that I could identify with,” Peck told The Huffington Post. “In contact with other humans, the filter through which everything you say is perceived is your voice. I was also really scared that I would not be able to sing any more. With these thoughts in my head an idea about singing as a way to show others my journey started to form. When I contacted my very talented friend, André Åhl Persson, who is also a musician, and he was willing and thrilled to do this project with me this seed of an idea started to grow.”
