April Morning is unique, to my VERY limited knowledge, in being the only English folk song I know in which nothing actually happens, inspite of the opening line. It merely presents a state of mind, in words of poetic simplicity. It is a presentation of love as a personal tragedy, which has a certain morbid quality to it; and which the second piece of music devlops.
"The Dream of the Red Mansions/Chambers" ("Hong Luo Meng" in Chinese) is one of the four classics of Chinese literature. It tells the story of the tragic love between Jia Baoyu and Lin Daiyu, a couple matched through the impossibly complex twists and turns of fate, but torn apart by circumstance. It is a terrifically affecting and brilliant novel. 
The sounds in the music follow quite naturally those in April Morning - the swooning 'cello which arrives at around 4 minutes 30 gives me the shivers every time, it's contrast with the plangent tones of the Pipa - a Chinese lute - could not be more perfect. Perhaps it suggests the shallowness of life and the depth of the other.
This is the final part of the complete piece of music, and was written to accompany the death scene of Lin Daiyu, the heroine. The transcendental qualities of the novel are recreated in the music - is Miss Lin dead, or just returned to her nature? That spookily repeated 'cello motif draws the listener into something deeper than can be imagined, a bottomless pool of...
Water, I know, is a favourite on Late Junction. I wanted to find a song which brought all this morbidity to a positive outcome. I'm not convinced that Water does this - it's too open - but it certainly fits the mood. In fact, when I first listened to this fantastic album, I found myself playing a guessing game to guess the titles of the songs - "Love" was easy, and "Fire" I got, too. But for "Water" I guessed "Death".
The drone follows the tone of the last piece completely, but it's the openness of the music which makes it work here - it gives a sense to the listener of having travelled through the tragedy of the first two pieces into a new place, of uncertainty and infinite possibility, which room for any and all thoughts which might drift your way. I think that by the end of the three pieces, they have created not so much a space for themsleves, but an entirely new place, a new feeling, a new life.
I think that Hong Luo Meng is not available in England, or anywhere else but China, for that matter. But I'd be delighted to send a copy if you want to play it, which I hope you will; or just have a listen. Everyone should own it.
I'm also aware that this is rather a long collection; but I challenge you to find a better way to spend 25 minutes of your life. And if you really have to cut it short, you could switch "Water" for Van Morrison's "Slim Slow Slider" - it is watery, too. It always reminds me of a summer rain after a storm; and it deals with mortality in it's lyrics. But it's not as great a finale as "Water".
