Purbayan has learned Sitar from his father Parthapratim Chatterjee-disciple of Pt Nikhil Banerjee and Ustad Ali Akbar Khan. Purbayan's music is inspired by the sound of Pt. Nikhil Banerjee. His music combines the tone and richness of the Nikhil Banerjee style and a contemporary touch of his own urbane sensitivity. He is also an vocalist in his own right.
