Rodriguez, the hero of Looking for Little Sugar Man, is more famous in South Africa than the Rolling Stones. His Cold Fact and Coming From Reality released in the 197s have sold more than 5, in this country with a population of only 4 million. However, the South African fans who can read countless reports about the Rolling Stones can't get any information about Rodriguez, and the only thing they have is the song itself and an unclear album cover. This aroused their infinite reverie, which led to countless rumors-some people said that he committed suicide by overdose in prison, while others said that he poured gasoline on himself in public on the stage and then set fire. In fact, Rodriguez has no idea about his brilliant achievements in South Africa. As a retired singer who was canceled by the company for decades, his real identity is a decoration worker in Detroit. It was not until Steven, the owner of a record store in Cape Town, and Craig, a music journalist, started a trip to find Rodriguez by chance that this unknown legend gradually surfaced. Due to the lack of video materials, the film was made up of interviews with people involved in the event, old photos and old newspapers. As a result, Finding Little Sugar Man, the winner of the 85th Oscar for Best Documentary Award, became an out-and-out film born on the editing platform. However, the film's sense of presence is greatly enhanced by the director's flexible application of sound effects. For example, in the interview at the opening, with the scenes inside and outside the bar on the day when two interviewees first met Rodriguez, "the freighter behind", "the noisy bar" and "the guitar protruding from the smoke wall" also sounded in the background sound. The repeated driving scenes, that is, the simple technique of "longitudinal movement", connect Cape Town and Detroit, 197s and today's world, which highlights the "seeking" atmosphere of the film. China fans who grew up in the era of piracy will surely have a deep voice about this: in a relatively isolated distribution system, only an enthusiastic music review article, supplemented by audio-visual publishers (that is, the favorite of cam-producers), some unpopular music can be "discovered" again, thus gaining a more enthusiastic response in a new country-the most typical example is Lacrimosa；; However, with the popularity of the Internet and English, the legendary "Little Sugar Man", which is very popular but unknown, will probably die with the physical record. In this sense, Looking for Little Sugar Man is not only a tribute to Rodriguez, a music hermit, but also a reminiscence of the past.
