Before becoming fascinated by the didgeridoo, Matthias studied soundscape and created music with everyday objects. His didgeridoo music is not centered in Australian examples or an aboriginal dream world. He is inspired by tones and sounds in his everyday surroundings. His musical interpretation expresses his own mood and physical state. At the same time, Matthias is interested in sounds created by similar instruments in different cultures, such as the didgeridoo and the alphorn, on which he has focused much attention since 1997.
Müller’s musical-theatrical interests go a step further, as he seeks contacts to other musical styles and art forms, such as mixtures of his primal-sounding music with traditional western music, jazz, funk and house or in projects with visual artists and video art.
In his performances, he likes to combine the didgeridoo with the traditional Swiss alphorn, creating an extraordinary dialog between cultures.
His performances offer entertainment for the eyes as well as the ears. During concerts he often moves through the audience with the lighter dreamtime pipe and fills the room with sound from all directions, giving sound a physical expression.
