M. Hario Efenur is a composer, researcher, and multi-instrumentalist of Minangkabau ethnicity who resides in Lasi, West Sumatra. He produces a diverse range of musical works, spanning from body music to experimental music.  Hario founded the music group Candasuara, inspired by Silek, the traditional martial art of Minangkabau. Through this group, he explores and composes the body sounds in Silek into new, more performative and interactive music compositions. By integrating aesthetic, kinesthetic, and social interaction elements in every performance, Hario aims to provoke critical thought about the role of the body as a source of sound and artistic expression.  Hario is also involved in various collaborative projects that combine music and visual arts, as well as delving into the application of technology in music composition. His works have been showcased on national and international stages, reaffirming his contribution to contemporary music development while expanding the discourse on cultural identity.
