Synesthesia
Charli confirms she has a form of synesthesia. For example, she can see music as colors.
For me, I’m not a very technical person. I can’t sit at Logic and make a track and I don’t know the terminology to do that. So, when I’m in the studio, I’ll be like, “Make it sound more like an ocean. Make it sound like blue with sparkles and dolphins” … I feel like to me, dubstep is like, the colours green and yellow and brown.
