In the mid-1950s Charles Mingus embraced the collective improvisation of early New Orleans jazz and the ecstatic worship and singing rituals of the Black Pentecostal church— two historical African-derived approaches that emphasized group expression.
Mingus used these two approaches to advance both musical expression and political and spiritual ideas, charting a trajectory toward group oneness. His recordings from the mid-1950s to the early 1960s progressed from short sections of collective interplay and group improvisation reminiscent of early jazz to longer forms of ecstatic ritual. This latter practice—in the form of solos, band, and audience participation—was a direct invocation of the spiritual communion or Holy Spirit possession that he had witnessed in Pentecostal church services as a youth.
This according to “Mingus in the workshop: Leading the improvisation from New Orleans to Pentecostal trance” by Jennifer Griffith (Black music research journal XXV/1 [spring 2015] 71–96; RILM Abstracts of Music Literature, 2015-87883).
Today is Mingus’s 100th birthday! Below, Wednesday night prayer meeting (1959), one of the recordings discussed in the article.
