An absolutely incredible online library of avant-garde film, music, poetry, and more — it's one of the few parts of the internet that is still a pure, universal good. You will almost exclusively find things that you cannot believe it exists or never thought to wonder if it exists, for example: this 1966 documentary about & featuring John Cage & Rahsaan Roland Kirk! They compare and contrast avant-garde classical and avant-garde jazz, and discuss* avant-garde music as a whole. It is beautifully and strangely filmed and is soundtracked with their beautiful and strange music. And this is just one of hundreds of incredible finds curated for free on UbuWeb. You don't need to sign up or enter your email address, you don't need to pay to remove ads -- all you need is curiosity. It's exactly what the internet was meant to be.
*The "discussion" doesn't happen verbally, but is done by the elements of the film itself, and by John Cage's poetry, intercut with Roland Kirk's live music
(P.S: If you don't know Rahsaan Roland Kirk, I only more highly recommend this doc — but you may recognize him if you saw a photo or video of him playing music in his distinct style of... playing 4 saxophones at once.)
(P.P.S: I would love if you shared here what you find there!)
