From Bengal to boogie: Rupa Biswas, India's rediscovered disco diva

After her album Disco Jazz sold a handful of copies in 1982, Rupa Sen Biswas faded into anonymity. All that was left was her first name on the album cover, on which she is pictured in a red dress, beaming and holding a cordless mic.

It was only when her son Debayan searched for her record online that they found it had been uploaded to YouTube, that original copies of the record were selling for more than £500, and that it was being reissued by the US label Numero Group.
