[5][6] A humble singer's brash lyrics ignite fame and fury across Punjab as he grapples with soaring success and brutal criticism before his untimely death.

Amar Singh, born in a Ravidassia Dalit Sikh family in Punjab was working in a socks manufacturing factory (much to his dismay) as a teenager, whereas his heart and soul were wrenched in creating music.

He started working under a known musician and singer Jatinder Jinda(Surinder Shinda), who acknowledged his talent and began to use his lyrics in his songs (without giving any credit to Amar Singh).

[7] The film follows the journey of Punjab's original rockstar of the masses, Amar Singh Chamkila, who was assassinated at a young age.

[8] Ali termed the film "a unique journey" for him and further added, "Shooting for Chamkila felt like a very different experience as a filmmaker.

[25] Lyricist Irshad Kamil and Rahman designed the songs rooted with rhythm changes and adapted them to the type of Broadway musical.

[29] Upon release, the soundtrack album received positive review from music critics who acknowledged the careful crafting on tunes, the mood, tone, beats and lyrical phrases.

[31][32] Amar Singh Chamkila's eldest daughter Amandeep Kaur showed disappointment with Imtiaz Ali.

She said Imtiaz Ali didn't do justice with the film by omitting the crucial moments of her family especially her mother Gurmail Kaur performing the last rites of her father.

[33] Amar Singh Chamkila received critical acclaim, with reviewers praising Dosanjh and Chopra 's performances, the film's soundtrack, and Ali's direction.

[37] Sukanya Verma of Rediff.com rated 4/5 stars and observed "Diljit Dosanjh's switch in singing style as he smoothly assumes Amar Singh Chamkila's vocal persona highlights the brilliance of his artistry.

"[39] Shubhra Gupta of The Indian Express rated the film 3/5 and wrote, "Diljit Dosanjh internalises Amar Singh Chamkila’s hard-scrabble life and pain, and distills it into his fine-grained performance, playing an artiste who lived and died by his beliefs.
