A better comparison of a music genre to abstract paintings would be something like this:

I get the idea that removing lyrics from a song makes it much more abstract but you really can't group the noisy pieces of shit in this thread with all the great works of music that had no lyrics.
A bunch of ~INTJs sitting in a gaming forum talking shit about abstract art is pretty cliche but I'm with Araysar and Fanaskin, so much modern art is a pile of shit and it's because cameras replaced the artist's historical role.
There's a ton of these prank videos but it's pretty effortless to just insert random shit into a contemporary art gallery and people will believe it belongs.

When an effortless prank is able to supplant your artwork, maybe it's time to rethink what belongs and doesn't belong in a gallery.
There are three parts in your post, let me address all three.
1) The gamut in abstract art is about as large as the gamut in music (and I'll pretend you were not dissing Steve Reich). For every hyper 'noisy' Jackson Pollock painting, there is an intense monochrome by Yves Klein or the serenity of a composition by Mark Rothko, etc, etc. The linearity of music, the fact it is an art of time, allows us to maybe project with more ease a kind of narrative continuity to it, but it is in no way less abstract than abstract painting. A C flat on the harpsichord in a Bach piece represents nothing other than itself; the sound you get when you press that key of the harpsichord. Yet, there are moods, there are movements, there are conversations in musical pieces. That's the power of abstraction (and an enigma to neurologists and sociologists): music cannot show sadness or tell sadness (or joy, or loneliness or rage) but it still can communicates it.
2) The idea that the camera replaced the painters' 'historical role' is assuming that their role was to make a realist representation of reality. You will find that outside some artistic movements delimited to specific times and specific places it was never the case.
3) As a general rule I hate pranks, because it's social manipulation + editing. In that specific case, an exhibition is curated so the visitors come with the expectation that someone, most of the time more knowledgeable than them on the topic of the exhibition, selected a number of artworks. With that frame of mind, most visitors will give the benefit of the doubt to what they see. Maybe they'll like it, maybe they won't, maybe they will find it worthy to be selected, maybe they won't, but they'll assume due diligence from the curator and, as such, will try to find in each piece what is supposed to be interesting (I confess that I often fail). A prank piece will be approached with an open mind, which is more a testament to the curiosity of the visitors than a proof that they are dumb or that modern art is stupid. In the particular example shown in the video, some might even like the piece, because there is something light, fun and incongruous about it (which, depending of the exhibit can be a nice change of pace), they might also like the prank itself as a performance commenting on art.
As a conclusion, an abstract visualization of a piece of 'noise' music, both requiring a high level of craftsmanship. WARNING DO NOT PLAY LOUDLY:
