I can attest to good music being made, but it's still very slow to evolve compared to the 2nd half of the 20th century.
Movies, books and widely played music are all closed avenues for 99.9% of artists. There's no way you'd get any kind of distribution worth the effort to produce such a large artifact. The most creative writing I've seen in the past 15 years has all been done as a series of posts or articles. The best genre bending music all seems to fly under the radar of most people because it only gets hosted on SoundCloud, obscure YouTube channels, and sold on indie online commerce sites, the same for short films which seem to be exclusively on YouTube or social media sites. Everything has to be DTC now, due in large part to the increase in gatekeeping by some of the platforms I mentioned like YouTube. You won't just show up in someone's feed because you're a good match for their interests anymore, at least not unless you've heavily monetized and sanitized your content to be acceptable to ad sales. So instead it all has to work on the indie model where you build your community along with your art. You have to be your own PR, run your own Discord, build your following, host your own events, etc. It's a struggle and it means your reach is just as limited as it would have been pre-internet when you were trying to do the same in your city using flyers, gigs, and word of mouth.

Easier said than done, but you just have to find some person or blog that has similar taste in movies to you, and listen to them.
As for my own work, I have a small group of friends that I write with in person, and I perform in person occasionally (most recently in the fantastic writers cafe Laidak in Neukoln in Berlin). I'm utterly terrible at marketing, and my work doesn't fit the demographic criteria for contemporary publishing, so you can't find much it anywhere online or off. That's likely true of a whole generation of writers who aren't creating didactic autobiographical morality tales. I don't want to dump stories or books that take months to write into the void of self publishing, but I'm a writer so I still write.
In terms of music - I just spent a few days in Berlin listening to live work at venues like Trixxter. If you're open to experimental live performance there are a whole bunch of scenes in small live venues. Again, not sure how you'd pick it out from the both the dross and the heavily promoted work online.
In terms of film, again my reference is Berlin - there's a whole scene right now that you might call antifilm (I have no idea if it has a formal name). Small films shot verite from life, without a budget, and wilfully rejecting any kind of formal aesthetics (think Dogma on steroids). Wilfully horribly shot on bad cameras, but often incredibly interesting in terms of their engagement with life as its lived now, hauntology, post internet art etc. In terms of specific filmmakers Jean-Michel Brawands work is interesting. There's a whole community around Sputnik Kino and similar small events.
