The Music of Joker: Folie à Deux, with Composer Hildur Guðnadóttir

We really wanted to honor the sound world that we had already established [from the first film]... so we didn't want to go too far away from it. We knew that there would be strings and there would be a cello connection… Well, it just so happened that my instrument that I used in the first song got stolen a week before the recording session. So I had actually intended to just use the same instrument, but the Gods of Creativity forced me in a different direction… So I came up with this idea of creating what I call ‘the string prison.’ It’s literally like an electric fence that’s playable... an electroacoustic, large scale, playable string instrument that formed this prison cell of very, very, very hot strings, that I played through another instrument.
