Interrupted system call is musical tandem investigating philosophical issues through conceptual sonic interplay, their hypothesis being that error is the source of meaning. They like to call their music "unfree impro", as they are trying to confront the predicaments of freedom in improvised music, provocing rather than reconciling emerging discrepancies. "In this contrast between difference and connection, intensities arise that ensure that the sound shakes us and, after a quick expire, leaves us in silence, faced with the question: Now what is this?"
