Thejas Krishna is an Indian composer, singer, lyricist and actor working in Tamil Cinema. He worked as a child artist in 2018 for the film Kaatrin Mozhi. Krishna had a hobby in music; coming from a family of screen actors, he often created beats and was noticed by Santhosh Narayanan in 2021. This lead him to do additional keyboard programming for Narayanan's songs for films such as Gulu Gulu (2022) and Jigarthanda Double X (2023). This changed when he signed on to ThinkIndie as "808Krshna" (a combination of his last name and the musical element for bass). He released his first Indie track, labelled as "Poratta Varatta". This song gained some notoriety as the music video included the last appearance of the late actor, G. Marimuthu.
