Jam isn’t a music video, it‘s a short movie with no dialogue. Jam isn’t a story focused movie, it’s an experimental piece of art that’s fully about the aesthetics. If you’re a fan of animation, and I mean literally the animation itself, you will likely enjoy this piece. It’s colourful, lively and there’s plenty going on. The work with shapes is nicely done, as usual for Mirai Mizue’s work. Jam does good what it sets out to be – an interesting short bit of moving scenery. It would be unfair to rate it low just because it doesn’t have a story – it was never supposedto have one.

If you’re a bit confused by this kind of content, I would suggest watching a bunch of short experimental anime to get more context for rating them, and surely you are likely to find out that some, like this one, are enjoyable just for their “vibes”, as the kids say. In worst case you’ll just lose few minutes of your life.
