Srinivas was born in a Tamil Iyengar family at Ambasamudram, Tamil Nadu, though his family moved and has since then lived his entire childhood in Thiruvananthapuram. He started listening to Semmangudi Srinivasa Iyer, M. D. Ramanathan and others through his aunt Mrs. Padma Narayanan, his guru in music. The soul-stirring magic of Kishore Kumar-R.D.Burman deeply influenced him in his childhood days. He went to complete his B.Tech from Bombay University, Department of Chemical Technology (UDCT, now known as ICT); during which he represented his university in youth festivals. After pursuing his career as a chemical engineer for 10 years, his passion for music got the better of him. In 1988, Srinivas approached music director Ilaiyaraaja, who was at the helm of Tamil film music then. He was offered the opportunity to work with Ilaiyaraaja, but however things did not work out, as he was suffering from severe throat infection that day. It was later in 1992, that the soundtrack of Mani Ratnam\'s Tamil film Roja reignited his dreams of playback singing. Mani Ratnam had introduced composer A. R. Rahman with this movie, who then went on to change the music scene on the whole Indian film industry. Encouraged by the use of fresh voices in Roja, Srinivas approached A. R. Rahman. Rahman took a liking to Srinivas\'s rendition of Mehdi Hassan\'s ghazals and offered him work at Chennai. In 1994, Srinivas shifted base to Chennai and started lending his voice to advertisement jingles and devotional albums. His first foray into playback singing began with the song Sorgam Enbathu Namakku from the movie Nammavar, composed by Mahesh. It went on to became a runaway hit. But it was only in 1996, that he gained recognition with the song \"Maana Madurai\" from A. R. Rahman\'s Minsaara Kanavu. Then came \"En Uyire\" in Mani Ratnam\'s Uyire (the Tamil version of Dil Se). This Rahman composition catapulted Srinivas into fame. Srinivas has sung for leading music directors like A.R.Rahman, Ilayaraja, Deva, Vidyasagar, and in languages like Tamil, Malayalam, etc. He has made a foray into music direction through the Tamil movie Ae Nee Romba Azhaga Irukke, in which he was one among the five music directors of the movie. And his composition \"Ini Naanum naanillai\" in that film is a major hit. His famous albums include Ussele Ussele and Paarvai. Also he has worked as a co-composer to Praveen Mani for Little John. He has also composed music for a Malayalam film titled Seethakalyanam. The playback singer from South cut his first private album in Hindi titled Yeh Duniya Sab Ki. His other hits in Hindi include \"Kaisi Hai Yeh\" from Dil Chahta Hai and \"Zindagi\" from the film Yuvvraaj. Srinivas is a close associate to A. R. Rahman from the very first day he got introduced to Rahman. Additional programmings and backing vocals for many of Rahman\'s songs are done by him. On working with Rahman, he says, \"There can be only one Rahman. Two years ago, he called me out of the blue to supervise his recordings. I consider it an honour. Earlier, he would be there to monitor every single take. I sometimes wonder if I can match his perfection standards,\" and adds, \"He\'s at lightning speed when it comes to creativity and innovations. There are times when he compliments me and nothing feels as good as that. For me, it's like an award" He is a judge on Airtel Super Singer, aired in Vijay TV along with Sujatha and Unnikrishnan. He also judged a famous music reality show named Gandharva Sangeetham, telecasted in Kairali TV, and in which Anuradha Sriram and Johnson were the other judges. In 2010, he released an album titled, Timeless Classics by Srinivas. This was a tribute to Mehdi Hassan and included major ghazals of him sung by Srinivas. It was released on Saregama and was launched by A. R. Rahman.
