Walter Nelson created this video that compiles all the dancing clips from the 1933 Argentine Film, “¡TANGO!”
The complete movie has also been made available by youtube user Victrola Tango Club:
Wikipedia informs me that the video’s sound quality is a problem inherent to the original recording. It was, apparently, the first film made in Argentina using optical sound technology.
Mr. Nelson’s fascinating youtube channel can be found here. His website, “Mass Historia,” can be viewed here.
