S.D. Burman had a sound base in Indian classical and folk music but could also be hip and trendy for his times, which helped him forge an easy connect with people. Despite the classical grounding, his songs had an endearing lightness and zest, a quality that still makes them sound fresh and contemporary. He remained much in demand till the very end of his life, even at a time when his own son, R.D.Burman, was on the rise.
