New Delhi, May 9 (IANS): Kanika Kapoor has crooned for a track of "Udta Punjab", which brings a dark story of prevalent drug menace in Punjab. And the singer says the song is different with a “dark and grungy” vibe to it.

Asked to describe the yet unreleased track, Kanika said: “The music on the whole is quite grungy”.

“It is about the movie... it is about drugs and all that. So my song, what I can talk about, is grungy, dark, a very different song but at the same time it is also a very Amit Trivedi song,” Kanika told IANS.

"Udta Punjab", directed by Abhishek Chaubey, highlights the issue of rampant drug abuse among the youth in Punjab.

Shahid Kapoor is seen essaying the character of a high-on-drugs, long-haired rockstar Tommy Singh, who sings with glee and abuses with impunity.

It features Alia Bhatt as a migrant Bihari labourer, Kareena Kapoor Khan as a doctor who is determined to fight the illegal transportation of drugs, and Punjabi actor-singer Diljit Dosanjh as a police officer.

Kanika declined to reveal more details about the song, which is picturised on Alia.

The singer, who has given hits like “Baby doll", "Chittiya kalaiya ve" and "Nachan farrate", said: “I can't say anything other than that it is an amazing song.”

Talking about highlighting social issues via songs, Kanika shared that “it is a great way of connecting”.
