One of experimental music's most noteworthy forerunners, Ariel Kalma, has been the recent subject of director Matthew McGuigan. Shortly after Kalma re-distributed much of his long-sought work from the '70s - An Evolutionary Music (Original Recordings 1972-1979) - McGuigan brought out his lengthy piece on the Paris-born marvel, taking a look at his all-world inspirations and impossible vision.

Kalma's career, while seeing a momentary resurgence, is remarkably undiscovered. McGuigan's task to indulge in upwards of four decades worth of iconoclastic movements is relatively impossible, but for his credit he allows Kalma to speak for himself roughly the entire time.

For the curious and music snob alike, Kalma's impassioned and impressive work is so furiously dense that any documentary won't die it justice in its entirety. But McGuigan does bring a fantastic re-introduction for him.
