ABOUT RASTAK https://www.rastakmusic.com/

"Rastak is one of the most well-known bands in Iranian contemporary folk music which formed as an experimental music group in 1997. The group seeks to collect, record and interpret Iranian folk music for a global audience; incorporating language, culture and history 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."

Rastak are apparently not a group in exile, but are living in Iran; the list on their website of previous concerts shows that they mainly perform in Iran although they have also made tours abroad.
