After the band had gone through several line-up changes, they've finally refined their sound and style in 2016. Adopting masked personas, they've added theatrical element to their on stage performance. Tales of the supernatural in Asian folklore, to the stories of the Pharaohs. O.S.R 313 aims to bring a new dimension of story-telling and nu-metal music. O.S.R 313 blends many ethnic South East Asian rhythm with Nu-metal elements mixed with groovy bass & guitar beats to great effect! This is best exemplify in their debut single DANSA.
