First of all, 4/5 and 4.5 stars.
The entirety of the track gives the distinct impression of something ominous going on - either a march to battle with the evil enemy, or a forced march of the evil enemy's army. I like it very much, but it strikes me as a background track that sets the scenes or montage in which the "Long March" takes place, rather than a marching anthem.
Two minor gripes:
The rhythms, transitions, repetition, and style of instrument utilization make this not really a track in the classical vein, but more along the lines of a movie or game soundtrack.
And for a track titled "the Long March," (which also makes me wonder if this is how the Chinese Communists felt when they went on their Long March retreating from the Nationalists) it's not particularly lengthy (although I'd be willing to wager that parts of it can be mixed and matched in various sequence combinations over a longer duration of time), nor is it consistently in the march style (e.g. the Russian national anthem, the North Korean national anthem, many Russian marches dating from the first three decades of the 20th century, the Battle Hymn of the Republic, the Marines' Hymn, and so on).
Just my two cents. Still a fantastic track though.
