Mohammad Reza Mortazavi (b. 1979, Iran) is a virtuoso percussionist known for his groundbreaking work with the tombak and daf, traditional Persian drums that he has radically redefined through new playing techniques and extended vocabulary. Mortazavi began playing the tombak at the age of six. By nine, he had already outpaced his teacher and won Iran’s national tombak competition — a distinction he would earn six more times. By his early twenties, he was widely regarded as one of the foremost players of the instruments. Since then, his music has continued to evolve, embracing new forms and vocabularies beyond tradition.

Ricardo Villalobos (b. 1970, Chile) is a pioneering figure in minimal techno, celebrated for his hypnotic approach to rhythm. Raised in Germany after his family fled Pinochet’s regime, Villalobos was drawn early to percussion — he began playing congas and bongos at eleven, developing a tactile relationship to rhythm that would later inform his distinctive production style. Immersed in both Latin American folk traditions and the emerging house and techno scenes of late-80s Europe, he began DJing and producing in the early 1990s, quickly achieving cult status within global club culture.
