Kamal Ahmed is a sincere patronizer in enriching Bangla Song, especially Tagore Songs. He tries his best to maintain authenticity of lyrics and tunes. He believes- “We can never explore the wholesome of Rabindranath Tagore through diffusing his songs only, we must also study Tagore’s life, literature thoughts and ideas.”
