Two short films featuring Sun Ra, the avant-garde jazz artist whose big band the Arkestra got its start in Chicago. I haven’t seen Phill Niblock’s Magic Sun (1968, 17 min.), but most accounts suggest its visuals may be more striking than its music. Whether this is true or not, the music in Edward O. Bland’s eccentric Chicago-made short Cry of Jazz (1959, 31 min.) is absolutely essential. The paradox here is that Bland’s film centers on jazz and needs various kinds of performance to illustrate its points, yet what’s being played is only adequate; if the music were good enough to distract one from the talk, the film wouldn’t work as well. Lucid and provocative, this is recommended viewing for any jazz novice, one of the best social readings of jazz form I know.
