On the subject of math rock, while not really a genre I enjoy very much, I do have some favorites. Here's some:
G.O.A.T-Polyphia:
Very virtuosic, tons of fun to (try to) play and just very new sounding.
In the Absence of Strong Evidence to the Contrary, One May Step Out of the Way of the Charging Bull - Don Caballero
This is kind of a deep cut by an underappreciated band, it's extremely complex, very unusual and energetic, which is what you expect from a math rock song.
Badger - TTNG
Another underappreciated band. This entire album is very pretty and all the songs are virtually impossible to play.
Frame By Frame - King Crimson
Alright, here's one for the boomers around! King Crimson isn't technically considered math rock usually, but imo they definitely fit the bill sometimes. This song has a very interesting main riff or rather two slightly modified versions of the same riff going in and out of sync, creating a very nice effect.
Drip - Tigran Hamasyan
OK, Tigran Hamasyan isn't usually considered math rock either, but he has a lot of math rock adjacent songs. This one isn't really one of the more mathy ones, but it is my favorite. Here's a nice video on the more rhythmically insane ones:
