His next big career break came when famed cinematographer Rajeev Ravi roped him for his directorial venture in Malayalam, Annayum Rasoolum.
He marked his debut in Bollywood with the Hindi remake of the hit Tamil film Pizza, by composing the background score of the movie.
[5] In 2017, a Telugu remake of the film was made by Chinni Krishna, named London Babulu, which featured music re-used from K's Tamil original.
The background music of the film was handled very maturely, leaving a lot of silent spaces, so as to not disturb the emotional and poignant storyline.
The highlight of the Ammani album was 'Mazhai Ingillaye', sung by the prodigious Vaikom Vijayalakshmi, who rendered the song pitch perfect, adding to the unique blend of Carnatic music and synth sounds.
K has composed the music for the 2023 German documentary, Sara Mardini – Gegen den Strom directed by Charlie Wai Feldman.
[27] K composed the background score for veteran director Prasanna Vithanage's film Paradise, presented by Mani Ratnam and Madras Talkies.
[30] K composed the score for Atul Sabharwal's film Berlin (2023), starring Rahul Bose, Aparshakti Khurana, and Ishwak Singh.
