Progressive metal.
One of my favorite bands has a song where it sounds like everyone is playing a different time signature simultaneously, and it feels out of time and chaotic… And then snaps into focus perfectly, before breaking up again. (I can’t identify the time signatures, no. I can hear at least two, and I’m pretty sure three. I think the drummer is doing polyrhythms?) You can listen to the same song five times in a row, focusing on a difference part each time, and hear something new each time. Or take Opeth’s “River”; the same same song seems to effortless combine elements of country, blues, 70s rock, NWBHM into something that feels both classic and new. (“New” despite being originally released in 2014.) Or, shit, An Abstract Illusion’s “Woe”; it’s nominally split into 7 tracks, but the lack of breaks between songs means that the whole thing flows into a single piece. Or, or or!, “Castaway Angels” by Leprous; Leprous stretches and strains the definitions of what metal is, and is not. While some of what they do is clearly metal, are they still a metal band?
The only thing that’s a real constant in progressive metal is that the bands all have impeccable musicianship.
I will always regret not learning to play drums; my parents insisted that I learn clarinet instead. (My brother got to play drums though. Bastard.) Oh well. I have too many hobbies to try and add another one at this point. :)
