Good question. The daily posts on this site focus exclusively on clips of progressive bands performing. And while in some ways that should be enough — just like what Louis Armstrong said when asked to define jazz: “If you have to ask, you’ll never know” — it might be helpful to learn more about the history of the genre.

To that end, I’ll collect prog rock documentary clips from YouTube, as I find them, below. Check back often — or at least occasionally — for the latest additions! You can also learn more by visiting some of the “Prog Links” in the sidebar.
