Have you ever stumbled on an album far outside of what you normally listen to that you were blown away by and loved immediately? Tell me about how you got "sucker punched"!
Or maybe it took a few listens? Either way nothing beats the feeling of something new "clicking". I've had this happen a good number of times, and it always triggers an obsessive dive into a new genre.
For me, I listen to a lot of different 'out there' genres, but mostly based in rock or hip hop zones. While talking about drone metal with someone, they gave me the extremely inspired recommendation of a minimal techno album by an experimental duo called Emptyset.
Having not really listened to much dance, let alone the experimental fringes like that, I haven't heard anything like it, Immediately felt like I had my mind blown and got obsessed halfway through the second track. Just how cold and minimal it was with the most analog possible sounds wasn't like much I had heard. It was a completely different sort of "raw" that felt like I learned of an entirely new approach to music that in retrospect felt incredibly obvious, like taking the same sort of focus on texture that a genre like drone does, but applying it to rhythm.
I ended up diving really heavily into power noise and industrial techno, and over the years gradually worked backwards to more traditional kinds of techno and house. And I bet if i tried to listen to some of the techno/house I enjoy now earlier, I probably wouldn't have been able to appreciate them like I do now without that "click" moment of listening to a far more experimental version of it.
