I believe djent traditionally focuses on whats sometimes refered to as binary playing where a lot of open strings are interspersed into the guitar/bass playing. The sound is also achieved by extra low tunings and sort of machine-like rhythm. It's kind of a nebulous term since I've heard people refer to bands like meshuggah as djent and what you've linked here is entirely different. From what I've heard, the term is mainly synonymous with the rhythm, binary structure, and low tunings like I mentioned before and not so much the vocal style used, etc.
I believe that Rob Scallon's video below is supposed to be a satire on the djent-like sound
The whole djent thing is funny because the style is nothing new at all. It was used in tech/death music for quite some time. However djent bands decided to hone in on the one sound and make it their focus.
Djent is totally a thing. You just need some bands to listen to is all.
Meshuggah Animals As Leaders -Particularly the Joy In Motion album Periphery Chimp Spanner TesseracT SikTh Skyharbor
That should be a pretty good mix for you. Animals As Leaders and Chimp Spanner can be a bit more technical, ambient, and instrumental. TesseracT has a bit of the above but with vocals and some screams. Periphery is interesting. Just listen to all of it and enjoy it man.
I love Meshuggah and i have to admit i didnt like the new album colossus at all at first but then last week i was drinking and just played it and it must have clicked or something because i just listened to the entire album and really liked it. kindo of weird.
Likely you just listened to simplified techdeath or prog. Folks boiled down techdeath and heavy prog to form djent. They took the sometimes odd time signatures, binary rhythms, and low tunings of techdeath and heavy prog sound and removed all the other more interesting characteristics :D
Jealous. I had to miss AAS and Plini when they rolled through Minneapolis.
I'd also consider AAS as djent, although I feel like that fades a bit with each new release. Slowly transitioning into a more straight up progressive metal with heavy jazz influences (which both have always been present).
I'm happy AAS didn't ruin the music with annoying vocals. :)
