The music is thoroughly enjoyable whether we decide to visit the sound spaces through meditation with our eyes closed or by focused, alert attention. The performances offer entertainment for the eyes as well as the ears. During concerts Matthias often moves through the audience with the dreamtime pipe (the lighter, American version of the didgeridoo made of cactus) and fills the room with sound from all directions. His instrument moves along people’s feet, slowly wanders through spaces bordered by heads, shoulders, and arms, passes close to ears, only to suddenly turn and continue in another direction. The music becomes a physical experience, which intensifies its colors, spaces and rhythms.
