Eternal Rust is a professional instrumentalist based out of the finance capital of India, Mumbai. It is a one-man neo-folk project. According to Varun, neo-folk is not a genre; it is a belief and a medium to narrate stories. "The dark side of nature is best described through folk music," says Varun. Eternal Rust uses folk music to tell stories of nature and its mysteries. His music is experimental and is open to other influences as well. This innovative element of Eternal Rust allows him the use of ethnic instruments like Kantele.
