Both of these videos are examples of variety theatre, a form that does not aim to tell a narrative but simply to present a sequence of different acts. Video #1 is a PBS documentary of a popular American form of variety theatre that flourished from the 1880s to the 1930s. The first part of the video, up to 58:12 timestamp, gives a general introduction to the form. The second part presents and interrogates the experience of black and immigrant performers in this time and country.
