Sutanu Mitra was born in Burdwan. He comes from a family which has a musical background. His father, Shri Nityananda Mitra, was a noted Rabindrasangeet
singer. His mother, Shrimati Shibani Mitra, played esraz in her youth. But she preferred private life to a public one.
Sutanu was trained in Indian Classical music from Professor Dr. Dhruva Tara Joshi early in his childhood for six years. He learnt Rabindrasangeet from his father.
Sutanu did his Masters in English literature from Burdwan University. He took to writing and debuted in 14th August: A Letter, a novel, which was published in 2015. It got some critical acclaim across the reading fraternity.
An awardee of Sangeet Prabhakar from Prayag Sangeet Samity, Allahabad, both in Classical music and Rabindrasangeet when he barely crossed the double digit figure of his age, Sutanu is a teacher of English. He has a keen interest in kite flying and bio-farming.
