Although the film defies a linear plot structure, it begins with a bilingual scrolling text in Hindi and English that indicates the dominant thematic that film is knitted with. The narrative meanders between the biographic moments of Siddheshwari Devi's life, that describes her relationship with her guru and her benefactor, intertwined with the mythic history of thumri and tappa as a musical form located in the medieval ghats, gullies and mansions of Varanasi. For Mani Kaul this film, was a “poetic documentary,” [3] in an interview he says: “in my own way, I have tried to bring poetry, documentary and fiction together. We would call it non-linear narrative.”[4]
Srikanth Srinivisan wrote in The Hindu that in Siddheshwari, instead of simply presenting biographical details or passively documenting the singer's artistry, Kaul turns the genre of cine-profile inside out, amalgamating literary, theatrical, musical and cinematic forms together to construct an experience of music. "The sprawling film blends multiple timelines, realities and geographies to sketch a unique portrait of the artist," he wrote.[5]
In a review for The New York Times, Caryn James compared the film with an abstract painting, "wildly open to interpretation". Siddheshwari is "beautifully photographed but impenetrable," he wrote.[6]
