In Carnatic music, all the South Indian languages have been used prolifically, in addition to the ancient classical Indian language, namely Sanskrit. The Telugu language, of course, has been especially widely used in the compositions. But there is a wide collection of this music in Tamil and also in Kannada, and to an extent in Malayalam. There are also a few songs in northern languages like Marathi, Hindi and Braj Bhasha and this adds to the rich variety of Carnatic music.
This song is a composition in Tamil by Neelakanta Sivan on Lord Shiva. This song Sambo Mahadeva is one of his famous compositions. It is in the Raga Bowli and is set to Roopaka Taala.
