Kaththi (soundtrack)

Development

Anirudh composed the theme music four days after signing the film, which was featured in the digital first look poster. He later added that the album would feature two theme music versions. In April 2014, two more songs were produced after which Anirudh confirmed that 3 of the songs were completed. The next month, Bollywood music director Vishal Dadlani sang a track for the film. In August 2014, Andrea Jeremiah and singer Adhi of Hiphop Tamizha had each recorded a song. Hiphop Tamizha said that he had used classic Tamil words in the song. Keba Jeremiah played the guitar for one song which he labelled as "a soul stirring melody". Lyricist Madhan Karky called one of the songs he wrote a "stylish folk number". Vijay was reported to sing a "love kuththu" number. In early September 2014, Vijay finished recording his song, titled "Selfie Pulla" and the team went to London to shoot its song sequence. Anirudh confirmed on 14 September 2014 that K. J. Yesudas had recorded a song for the film.

Ma Ka Pa Anand hosted the audio launch along with VJ Priyanka. Anirudh and Hiphop Tamizhan Adhi were part of stage performances.
