Murray Lerner, premier film-maker once again produced a first rate concert film, marked by his ability to let the band do the talking, so to speak, by their performance. Very tough job to accomplish. Few producer-directors are able to subordinate themselves to their subject. Aside from a minimum number of audience shots to remind us of what the introductory note tells us (and that is all it is,  one or two sentences of text to set the context) there are something like 600,000 people out there and it is 2 AM so we know they have seen a good many acts before this one.
