In 1981, singer Rupa Biswas traveled from her home in Kolkata, India to Calgary, Alberta, Canada, where she recorded the album Disco Jazz. It was not a commercial success, but found a second life many years later, with copies of the joyful, genre-blurring LP selling for more than 500 pounds before it was eventually reissued by Numero Group. We connected with Rupa and her son Debayan for a conversation about the album's creation and how it continues to spread happiness so many years later.
