You're listening to Song Exploder, where musicians take apart their songs and piece by piece tell the story of how they were made.

I'm Rishi Kesh Hirwe.

I love talking to musicians about how they made their songs for Song Exploder, but I also just love talking about music in general with people who are passionate about it, just as fans.

And I'm really fascinated by how much power there is in music to change your life.

Just a chance encounter with a song that really hits you, it can really transform the way

you think.

Not just about music, but the way you see the world or see yourself.

It's happened to me multiple times.

And so I wanted to start a new conversation series

where I could explore how that's happened for other people.

In addition to regular Song Exploder episodes,

I'm excited to introduce a new monthly series on the podcast called KeyChange,

where I talk with fascinating people about the music that's

transformed. For this first episode, my guest is Sophie Thatcher, an actor and musician

whose credits include starring in the TV show Yellow Jackets, the film Heretic, and the new movie

Companion. I met Sophie through Companion because I composed

the score to the film. One of the pieces that I wrote is called Iris's theme based on

the character that Sophie plays in the movie. And after I wrote that piece, I found out

that Sophie is a musician and singer herself, so I asked her to record the vocals for the track.

It sounds like this.

So I got to know Sophie a little bit through that,

and we started trading music with each other, some of our own music and music that we're just fans of. And I asked her if there was a piece of music that she felt had changed her, that had transformed her in some fundamental way.
