What are the excellent documentary soundtracks?

If you want the soundtrack of a documentary, you'd better like to watch it yourself. Then search the soundtrack according to the documentary. At present, documentaries are mainly produced in Britain, America and Japan. We also have CCTV, but there is no famous soundtrack, and some of them also cooperate with BBC. The best documentary is undoubtedly the BBC, and the most popular BBC is undoubtedly Attenborough. I love chasing his movies, and his soundtrack accounts for most of the famous ones. There are many American departments, such as PBS, Discovery, National Geographic and movies, but the soundtrack is not very famous. There are not many famous records. IMAX movies also account for a large part, but if you find a soundtrack, it is very few. Another way is the Oscar for Best Documentary, and you can find all the lists. Then I went to find the soundtrack one by one, but strangely enough, I didn't like those Oscar films very much, so I didn't pay attention to the soundtrack either. . In this regard, interested people can also find a lot of OST. There are CDs. In Japan, the soundtrack of NHK is often famous, but I don't watch many documentaries. I remember just watching the thinker's documentary trilogy of the Forbidden City. Other documentaries are about electric donkeys by NHK, and I have seen many films, but I haven't seen any records in the films. The Japanese department is extremely powerful. Let's not talk about it. I can't talk about it Japanese is mainly because the music is much more famous than NHK documentaries, and NHK movies are not downloaded systematically. I've seen most English documentaries with the above pictures, but I've never seen a documentary with a well-known soundtrack related to NHK. For example, Kiyoshi Yoshida's Japanese on the Peaceful Moon has been popular for almost 20 years, but I believe few people have seen this documentary. We only heard it when we were reading the introduction. Oh, what is this? The soundtrack of an NHK documentary. Then we listen to records. That is to say, the Japanese documentary soundtrack can basically be a completely independent record. Another example is Dunhuang, Three Gorges and Taro Iwashiro in Kitaro. What documentaries are they? I haven't even seen it. Sino-Japanese friendship has passed, and the documentary is very old. Personally, I don't see much NHK, which is inconsistent with the record. Let's not talk about Japan here It takes a super expert to make it clear. My skills are far from enough and unsystematic. Also, there are many biographical films, including musicians, such as Mike, Mozart, Pollock, Van Gogh and so on. They are all movies, and they all have OST, but they are not documentaries. If you really want to say it, it will be endless. In addition, Disney has produced many documentaries, such as bears, monkeys, orangutans, cats, etc. Some BBC composers also go to Disney to compose music. But I can't download the soundtrack.
