Training and career
Sandhya started her music training under the direction of Pandit Santosh Kumar Basu, Professor A T Kannan and Professor Chinmoy Lahiri. However, her guru was Ustad Bade Ghulam Ali Khan, followed by his son Ustad Munavvar Ali Khan, under whom she mastered Indian classical music. According to Manorma Sharma, "Sandhya has been able to maintain her popularity as a classical vocalist even after acquiring the gloss and the glow of playback singing..." Though classically trained, the bulk of her work consists of Bengali modern songs. She began her career in Mumbai singing Hindi songs, starting with a song in the film Taarana in 1950. She sang, as a playback singer, in 17 Hindi films. She decided to come back to and settle in her home city Kolkata in 1952 due to personals reasons. She married Bengali poetShyamal Gupta in 1966. Gupta went on to write the lyrics for many of her songs. Her best known collaboration is arguably with the Bengali singer Hemanta Mukherjee with whom she sang numerous duets, primarily as playback for Bengali films. Hemanta and Sandhya became known as the voices behind the pairings of the Bengali superstar Uttam Kumar and his numerous heroines, most notably being the actress Suchitra Sen, whose singing voice she became. Besides Hemanta Mukherjee's compositions, her largest body of work is with Robin Chattopadhyay and Nachiketa Ghosh. During the Bangladesh Liberation War she joined the mass movement among Indian Bengali artistes to raise money for the millions of refugees who had poured into Kolkata and West Bengal to escape the fighting, and to raise global awareness for the cause of Bangladesh. She assisted Bangladeshi musician Samar Das as he set up the Swadhin Bangla Betar Kendra, the clandestine radio station broadcasting to Bangladesh and recorded several patriotic songs for him. On the occasion of the release of Sheikh Mujibur Rahman, the imprisoned leader of the new country of Bangladesh, she released a song Bangabandhu Tumi Phirey Ele.
