A while ago I came across a widely-seen Youtube video about the history of the Amen breakbeat, which was a reposting of a recording of a 2004 documentary audio installation by artist Nate Harrison. It details the artist's view of the rise of the break, as well as what this might tell us about the effects of intellectual property on cultural development.
Can I Get An Amen? — Nate Harrison (2004)
Having enjoyed the piece's dry-yet-engaging style, as well as learning about such a specific cultural phenomenon in some detail, I sought out other pieces by the same artist. Luckily, they're posted on his online gallery, as well as on Archive.org. Several of them are somewhat-abstract video installations which are less interesting to me, but there are several other audiovisual essays which I have enjoyed, on various aspects on art, media and tools.
