“I’m sorry to keep saying it, but I don’t love you anymore, Helena.” Those are the words that haunt our heroine (Eugenia Ramirez) throughout The Tango Singer, spoken by her live-in boyfriend who abruptly dumps her for another woman. Of course, Helena wouldn’t have discovered his motives had she not been following him—and hoping to see him one more time, and repeatedly calling him as quickly as she can re-speed-dial. While her personal life is in shreds, though, her professional one is on the upswing, with a major theater offering a residency to Helena and her band—contingent, of course, on whether she can set aside her grief and show up. For a film involving tango music and a freshly broken heart, Diego Martinez Vignatti’s Tango Singer is fairly low-key. Viewers are treated to many lovely and often aching performances by Ramirez, whose character better expresses herself through song than conversation. (There’s a lot of quiet staring going on.) But at times the story is too understated, favoring images over exposition, and it can get confusing about where Helena is (summaries say she moves from Buenos Aires to France) and the choices she makes (out of nowhere, for example, she’s shown working at a bakery). Just as you’re getting frustrated, though, the film closes so elegantly and perfectly that all those details seem inconsequential—this is about Helena and her recovery, regardless of where she is on the map.
