Smith who contributed guitars, noises, and samples to the track. Eluvium’s Matthew Cooper said, “Mark and I have been friends for a long time. He is an extremely talented and creative person who explores sounds from many different angles. Having him involved on this was, quite simply, a lot of fun.”
