National Film Award recipient Anupam Roy considers the “groove” of the Bob Biswas soundtrack its unique selling point. “Not many songs have released in this [flavour],” says the composer of the Abhishek Bachchan starrer, a spin-off of the 2012 offering, Kahaani. “The brief given to me was that this is a revenge track. [The protagonist] has suffered a lot; he wants to get back at those [who’ve hurt him]. We roped in Siddharth Kaushal. He came up with the words, ‘Mujhe mujhse kaun bachaiga, tere bin’. So, it is a [revenge track], but also has a love angle. I crafted the number with a dark and gritty [undertone],” says the musician of the song that was rendered by KK. 

Roy shares composing credits with Vishal-Sheykhar. He admits that while the quality remains unaffected, he finds himself more “invested” in projects that seek his involvement in entirety. “When you compose one song, the investment is a bit skewed. For instance, with Piku, for which I handled the score and songs, I had an idea of the story and how my work would be [showcased] in it. I was hence, deeply connected with the film. Building that connect is crucial, and that comes about when you get to handle the entire album.”
