Rastak is one of the most well-known bands in Iranian contemporary folk music, which was formed as an experimental music group in 1997. The group seeks to collect, record, and interpret Persian folk music for a global audience, incorporating language, culture, and history, while also merging traditional instruments and forms with contemporary rhythms. For the past two decades, the ensemble's experimental work has focused on the sonic features of Iranian folklore and diverse cultures; the fruition of which has been research and fieldwork, film and theatre music composition, five music albums, and numerous domestic and overseas concert tours.
