Elis and Tom: Roberto de Oliveira and Jom Tob Azulay’s documentary looks into the backstage of “Elis & Tom” album recording, one of the most famous and influential of Bossa Nova, which contains arguably one of the upper-echelon songs of Brazilian music, “Águas de Março”. Listening to it, it’s hard to imagine how conflictual it was, at first, so in that regard, the film explores that nicely. Some of it pops from the very intimate 16mm filming done at the time; not that the interviews (from people close to the process at the time or some others) are uninteresting, but they are far from being as enticing as the archival footage. Perhaps that footage exists, perhaps not, but the film would gain immensely with more direct observation of Elis Regina and Tom Jobim interacting. In any case, some context is always welcome. Ultimately, how much one likes music, in particular Bossa Nova, will be the main factor to measure the enjoyment this documentary can provide.
