Before I even make the music, I draw out the performance in my head. After I think about the overall mood, outfits, props, dancers’ movements, and the character of whoever is singing the song, then I write the song and participate in the choreography and costumes before eventually going on stage. When creating a performance, what is just as important as the music is the fashion.
