Sun Ra & His Myth-Science Arkestra - The Nubians of Plutonia (2014)

Research herewith on vocal ensembles for tracks 5 and 11, variously identified by historians as The Nu Sounds or The Cosmic Rays: These groups are not the same ensembles, nor do they have overlapping members. The actual vocalists on these tracks might not be either group (the original Saturn LP back cover says "Arkestra" on "Africa"). Lacking session logs, any identification of vocalists on these tracks is speculative. The vocalists on "Black Sky" are unknown and could have been overdubbed at a date later than the original recording.
