Explanation:

Bishnu Prasad Rabha was an Indian cultural figure from Assam, known for his contributions in the fields of music, dance, painting, literature as well as political activism. As an advocate of people's cultural movement, he drew heavily from different genres of classical and folk cultural traditions. Considered a doyen of the Culture of Assam, the Assamese people affectionately call him Kalaguru (meaning: "the master of the arts"). He is also called by Marxists as Sainik Silpi (sainik "soldier", silpi "artist") for his active participation in the armed struggle, led by the Revolutionary Communist Party of India (RCPI).
