Filmmaker Shakti Hasija got to know musician Karsh Kale over a period of one and a half years, beginning sometime around 2016. But it's not that the two of them exchanged notes about their lives for hours on end, sipping coffee or something stronger to keep the conversations going.

Instead, Kale met Hasija briefly and gifted him around 35 hours worth of archival footage that traced his career, along with about 1,000 hours worth of his music. The latter took his time in poring through this material, imbibing the information contained therein to get a clearer picture of a person he barely knew. It's because Hasija, at that point in time, was in the process of making a documentary — or 'rockumentary' — that traces the life and work of a man who is considered a pioneer of the Asian underground and Asian massive movements in music.
