A fascinating live document that captures Sun Ra & his Arkestra performing an eclectic set for a Cleveland audience in 1975. Though the recording quality leaves something to be desired, this remains an inspired performance and includes a chaotic take on Duke Ellington’s “Sophisticated Lady” as well as “Astro Nation,” a clamorous foray into disco rhythms that anticipates Ra’s pioneering 1978 effort Lanquidity.
