Hauser recalls being fascinated as a child by the sounds of drum rolls at the circus; in his teens, the percussionist was attracted to the music of rock bands like the Beatles and Rolling Stones. Hauser has collaborated with such new music luminaries as Urs Leimgruber, Marilyn Crispell, and Joelle Leandre, but he is perhaps best known for his work as a soloist. While much of his solo music is improvised, Hauser also performs notated pieces written by himself and composers such asJohn Cage, Pauline Oliveros, and Pierre Favre. Much, if not most of Hauser's recorded work has been issued by the hatART label.
