Like the late great M.S. Subbulakshmi before him, Krishna sings in multiple Indian languages (Hindi, Bengali, Gujarati, Marathi, Kannada, Malayalam and English, besides Telugu, Sanskrit and Tamil in which Carnatic music is traditionally rendered). Astonishingly polyglot, at least in music, he is able to sing the works of medieval bhakti poets Tukaram, Tulsidas and Narsi Mehta, modern poets Rabindranath Tagore and Subramania Bharati, as well as the canonical repertoire of the established Carnatic trinity, Thyagaraja, Diksitar and Syamasastri. Unlike MS, though, he has not so far sung film songs whether in Bollywood or the southern movie industries (though he has gone on record with his assessment and appreciation of film composer-singers Ilaiyaraaja and AR. Rahman, both fellow-Tamils, in their own domain as popular and successful as Krishna).
