Through the skilful use of a small device at his feet, the „Loopstation“ (known from Ed Sheeran and Tash Sultana, among others), various instruments quickly merge into complex arrangements. In addition to his voice and his 12-string guitar, he also uses unusual instruments such as didgeridoo, bones, Irish flutes, and darbuka (Arabian drum) and some more. The viewers then experience up close how a song is created. Marcus also likes to involve the audience spontaneously, e.g. as a “background choir”.
