Since when did rocks cry out? Where on earth did this idea even come from? Straight from the Bible, that’s where. This piece is in the tradition of a true spiritual but has a known author, Hall Johnson. I had a hard time nailing down whether or not Johnson actually wrote the song or simply arranged it, but I managed to come across this clear statement: “’Ain’t Got Time to Die’ is an original Spiritual with words and music by Hall Johnson.” (“The Hall Johnson Concert Spirituals“) Let me quote Mr. Johnson himself on the subject of this music:
True enough, this music was transmitted to us through humble channels, but its source is that of all great art everywhere—the unquenchable, divinely human longing for a perfect realization of life. It traverses every shade of emotion without spilling over in any direction. Its most tragic utterances are without pessimism, and its lightest, brightest moments have nothing to do with frivolity. In its darkest expressions there is always a hope, and in its gayest measures a constant reminder. Born out of the heart-cries of a captive people who still did not forget how to laugh, this music covers an amazing range of mood. Nevertheless, it is always serious music and should be performed seriously, in the spirit of its original conception. (Wikipedia)
Of all the spirituals I’ve sung with my own choir, this one, with its slow pace and minor key, conveys the feelings of an oppressed people the most strongly. It’s not just a series of complaints or calls for help, though. There’s a lot of scriptural truth packed into it.
The simplified explanation of how black spirituals came about goes like this: slaves heard about Christianity after arriving in the US and, especially on the southern plantations, came up with sung versions of those teachings that gave them hope of a better life, expressed their longings for deliverance, and often served as rhythmic work songs. All of this is perfectly true but raises further questions: how did this “hearing about Christianity” come about? And why, if you think about it, would slaves adopt the religion of those who had enslaved them? Wouldn’t they see that religion as massive hypocrisy on the part of the slave owners? There’s also a tendency, which I have unfortunately shared, to think of spirituals as rather primitive. But that tendency is clearly mistaken: these are songs with deep meaning, displaying a breadth of Scriptural knowledge. To quote a modern African-American scholar and preacher, 
Several interesting (to me, anyway) questions to be answered about what the angels said to the shepherds on Christmas night.
What’s distinctive about Ron Jeffers is that he’s a living composer who has produced a significant amount of original music and arrangements, all for sale as sheet music from various outlets including his own company, Earthsongs, and whose music is performed quite frequently if YouTube is anything to go by, and yet . . . he has no online presence whatsoever. No personal website. No blog, No (worst of all) Wikipedia entry! How is this possible? In fact, if I hadn’t looked under “Ronald Jeffers” instead of either “Ron Jeffers” or “Ronald Harrison Jeffers,” I wouldn’t have gotten much information beyond his date and place of birth and a list of his publications.
