Sun Ra Arkestra

From the mid-1950s to his death, Sun Ra led "The Arkestra" (a deliberate re-spelling of "orchestra"), an ensemble with an ever-changing name and flexible line-up, although certain core members remained with the group through its various incarnations (Marshal Allen, John Gilmore, June Tyson, and others). It was by turns called "The Solar Myth Arkestra", "His Cosmo Discipline Arkestra", the "Blue Universe Arkestra", "Myth Science Arkestra", "The Jet Set Omniverse Arkestra", and many other variations. Sun Ra asserted that the ever-changing name of his ensemble reflected the ever-changing nature of his music.
