There are three of them and they do almost everything with their voices. Each does something different. Magdalena has a pure, emotional voice, totally committed in every millisecond of her performance. Her total involvement in music on stage seems incredible. Zgas does the human beatbox, changing completely the meaning of traditional hip-hop beatbox style. He produces a palette of sounds that has probably never existed before. Michael, surrounded by equipment, uses his bass voice as a background for the others.
