Rani Jambak, a prominent composer, producer, field recordist, instrument designer, and vocalist of Minangkabau heritage from Medan, is deeply engaged in exploring electronic music and soundscapes sourced from various regions across Indonesia. Her extensive body of work frequently examines themes surrounding nature, socio-cultural dynamics, and the intricate relationship between humanity and ancestral heritage.

Pursuing a profound exploration of cultural identity as a Minangkabau individual, Rani's artistic practice delves into the philosophical dimensions of Minangkabau traditions and investigates how ancestral wisdom can offer responses to modernity. Additionally, her work envisions the concept of future ancestors, grounded in spiritual values that are critically essential in contemporary life.

As part of her creative endeavors, Rani has designed instruments inspired by the traditional Minangkabau watermill, Kincia Aia. This innovation serves as both a critique of the climate crisis's impact and an effort to reinterpret ancestral knowledge in a novel dimension. Moreover, Rani, in collaboration with Hario, has developed performances rooted in the 19th-century manuscript, Tambo Alam Minangkabau, in partnership with Naskah Sumatra of SOAS University of London. In 2025, she introduced her installation piece, Pusako nan Sabana Tinggi (The Most Precious Legacy), a 20-minute sound composition featured at ASIA Topa. And a development work of Hario's Body Sound Performance of Silek Minangkabau with interactive electronic set by Rani Jambak and live coding by Scott Wilson premiered in BEASTFEaST 2025 Southeast/Northwest

In recognition of her groundbreaking contributions to sound, music, and technology, Jambak received The Oram Awards in 2022.
