Theatre: Playwright and director Purva Naresh talks about going digital with her play Bandish 20-20000Hz Director Purva Naresh Purva Nareshâs 2017 play Bandish 20-20000Hz is part of this yearâs Aadyamâs Digital Edition. The highlight of the play, apart from the terrific performances by the ensemble cast, is the glorious music direction by legendary Hindustani classical singer, Shubha Mudgal. The word âbandishâ is a homonym: it is a term used for a Hindustani classical music composition, and it also means âbeing boundâ. While 20-20000 Hz is the hearing range of human beings. The play is a story of two ageing stars of yesteryears â one a nautanki singer and the other a baithak (classical) singer â who come face-to-face in the green room of an Independence Day function. As they take an anecdotal journey back to their glory days, what unfolds is a tale of various kinds of restrictions or âbandishesâ placed on art and artists down the ages â be it political bans or social exclusions, threats from the people in power, to now the social media trolls.
