A student of Alathur Venkatesa Iyer, Srinivasa gave his first performances when he was ten years old. Together with Venkatesa Iyer's son Sivasubramania Iyer, he formed the successful duo known as the Alathur Brothers. He was awarded the Madras Music Academy's Sangeetha Kalanidhi in 1965. From 1944 to 1968, he was a court musician for the Maharajah of Travancore.
After the death of his musical partner, Alathur Sivasubramania Iyer, Srinivasa Iyer continued his concert career as a solo performer.
