full_context: Document 1: Kenneth Jones (songwriter): Kenneth Jones (1952–1969), was the son of Helen Myrl Carter (of country music's Carter Family) and of Glenn Jones. He is best remembered for a song he wrote called "Sing A Traveling Song" which appeared on Johnny Cash's albums "Hello, I'm Johnny Cash" and "Johnny Cash at Madison Square Garden". Kenneth was Cash's nephew-in-law. Cash's second wife, June Carter Cash, was Helen's sister. Kenneth, or Kenny as he was also known, wrote many songs and was a talented musician. At the time of his death he was under contract with Monument Records and appeared destined for a highly successful career. Following his death the Carter Family recorded one of his songs, "2001 Ballad to the Future". A few have noted the lyrics as being eerily prophetic of the September 11, 2001 terrorist attacks on the United States which took place more than thirty years after the song was written.

Document 6: M-Base: The term "M-Base" is used in several ways. In the 1980s, a loose collective of young African-American musicians including Steve Coleman, Graham Haynes, Cassandra Wilson, Geri Allen, Robin Eubanks, and Greg Osby emerged in Brooklyn with a new sound and specific ideas about creative expression. Using a term coined by Steve Coleman, they called these ideas "M-Base-concept" (short for "macro-basic array of structured extemporization") and critics have used this term to categorize this scene’s music as a jazz style. But Coleman stressed "M-Base" doesn’t denote a musical style but a way of thinking about creating music. As famous musicians did in the past, he also refuses the word "jazz" as a label for his music and the music tradition represented by musicians like John Coltrane, Charlie Parker, Louis Armstrong, etc. However, the musicians of the M-Base movement, which also included dancers and poets, strived for common creative musical languages, so their early recordings show a lot of similarities reflecting their common ideas, the experiences of working together, and their similar cultural background. To label this kind of music, jazz critics have established the word "M-Base" as a jazz style for lack of a better term, distorting its original meaning.
