This has been getting confusing. Many, many years ago before I ever joined this forum, djent was a style of palm muting Meshuggah (most notably) often used and it sounds EXACTLY like the example the Dude posted. That's what it sounds like when you mimick it with your mouth - djent djent djent!!!!!! Now the term has evolved into describing a style of music, but I don't really understand how.
That's what is so damned confusing. The bands that are supposed to be "djent" sound nothing like Meshuggah from a songwriting and a production standpoint. There have been bands and people like Misha who have mentioned their influences such as Meshuggah.
IMO the guitar tone of ALL the Meshuggah albums has never been what has been defined as djent. I remember when I first hear Bleed back before the album was released thinking, "those guitars have some chug to them". Nothing like bands such as periphery are doing today.
The only similarity I can see of Meshuggah to any other "djent" band is in the sognwritting, the polymeters, but the new wave of "djent" bands have gone on their own tangent in terms of musical and production structure to where they are nothing like the very band that influenced them to have their sound.
Today though, my definition of djent has always been from the guitar tone, and the pinnacle of that tone was brought to fame by Misha, therefor, the best example would be to listen to the guitar tone of Periphery, that is Djent.
This guitar tone is djent, that is the current definition, it is nothing more than that, if you want to talk about what it previously ment, that is a whole other debate:
I can oversimplify:
Old meaning: odd polymeters
New meaning: Periphery guitar tone/production
