Key Change is a new conversation series within Song Exploder, where I talk to fascinating people about the music that's transformed them.

My first guest is Sophie Thatcher, an actor and musician whose credits include starring in the TV show Yellowjackets, the film Heretic, and the new movie Companion. I met Sophie through Companion, because I composed the score to the film, and she contributes vocals to a few of the tracks I wrote. For this episode, we discussed how "Waltz #1" by Elliott Smith shaped Sophie's tastes and work.
