The four go-pro videos, the original videos have five different soundtracks to choose from. This is only possible to see with VCL player. I asked the four migrant performers to put on a GoPro for a day and they had to do three tasks: Talk to someone you know, talk to a stranger and transport yourself; otherwise, you are free to record whatever you want to. The soundtracks are the real sound, the performer reflecting on what he is doing, there are the three scientists commenting on what he is doing. So this is a way to try to make an experiment with different perspectives on the videos.
