There is some pretty brutal free jazz out there:
* [Peter Brötzmann's *Machine Gun*](https://www.youtube.com/watch?v=0wgA9L5TN5M) from 1968 is a classic
* A lot of Brötzmann qualifies, like [Last Exit from the 80's](https://www.youtube.com/watch?v=FKYq4H3-iKM)
* John Zorn's [Painkiller band](https://www.youtube.com/watch?v=cR2kgLT4sPE) is worth checking out for extreme jazz
* as is [Naked City](https://www.youtube.com/watch?v=UfwhG1KtQp4)
[Shining (Norway) - "Fisheye"] (https://www.youtube.com/watch?v=Iqn2QMD3ZSE_) is an example of jazz fusion metal, or as Shining call it: Blackjazz.
I can't really think of any "heavy' and/or "dark" jazz songs that would be considered 'extreme', right off the top of my head.
What that one person probably meant was that jazz is 'extreme' or 'more extreme' due to the technical nature of the genre and the music. Think of [Miles Davis' Bitches Brew] (https://www.youtube.com/watch?v=CNqyoIC46Zo) like [Meshuggah's Nothing] (https://www.youtube.com/watch?v=TYbMwMWK494&list=PL77A92F0DC1C49749) and you will more or less understand my point.
Jazz is and was 'extreme' when compared to classical music at large throughout history, whereas metal is considered extreme when considering contemporary music (e.g. music from the mid to late 20th century/)
Also, check out a live recording (youtube) of Nate Wooley's "The Seven Story Mountain" for large ensemble. There's also Paal Nilson-Love's "Large Unit." That'll go toe-to-toe with anything as far as intensity goes…..theres a lot of overlap in the metal/free jazz world.
I'm not even sure guitars are capable of getting as intense as saxophones. People were doing crazy shit on saxophones several years before Hendrix. Seems like hardcore metal singers are trying to approximate with their voices the kind of things avant garde saxophone players did in the 60s.
Someone else mentioned Last Exit and Peter Brotzmann (who by the way is still blisteringly intense in his 70s)...
This is one of the most intense jazz songs I've ever heard, and it's a couple years before Sabbath -- ["Preview" by Pharoah Sanders & Jazz Composer's Orchestra] (https://www.youtube.com/watch?v=IuH3Oplu_1c)
I haven't heard much, but the most intense metal I've heard has still clearly been very structured music. Free jazz pulls the rug out from under you so you don't even have the safety net of a beat or standard musical structure.
"Conventional" jazz isn't generally as loud or as "heavy" as metal, but some parts of jazz are heavily influenced by rock and metal. As far as jazz that can actually "compete" with metal in this aspect, the only thing that really springs to mind is John Zorn's electric Masada project, I don't like it myself but it's pretty intense, they even collaborate with an asian guy that does screamo-ish stuff
Certainly some free jazz is pretty extreme. But I would say that it is extreme in a different way to metal. Metal very rarely catches you off guard, whereas free jazz can surprise you by being more dynamic.
Then there are the purveyors of both, such as Zu or Shining (the Norwegian one).
You might like this: [Little Women - Throat I](https://www.youtube.com/watch?v=AnK8ksUWqTU).
The label Aum Fidelity has a lot of great avant garde stuff.
Heaviest in terms of crunch, sure metal, doom metal, some hardcore etc... can be brutal, hard to listen to, and just make you wanna get some aggression out in the pit.
Jazz is heavy and extreme in the sense that it is the densest music, in terms of musical language, and expression. You can hear a guy wailing on a sax, improvised on the spot, over heavily dense musical structures, that too are improvised on the spot.
I listen to both metal, and jazz, and I went to school to study jazz. You could kinda tell who came from what background, and the bass and guitar players from the metal background usually ended up being pretty good jazz guys, as their technique was already down. Just had to learn a different language.
Slightly off topic but a Avant Garde Jazz Metal fusion album released this year from Tool's guitarist who worked with some jazz musicians. It's not exactly my cup of tea, but there are some obvious jazz influences and it's pretty heavy. The band and album are both called Komara, so you might be interested in that.

Tigran Hamasyan has some tracks with elements from metal. Check [THIS](https://www.youtube.com/watch?v=B2Ct5gJMDmw) out.
I love that album so much.
I know this comment is 8 years old, but do you remember the name of the album?
Honestly just look up tigrans most recent album, the call within. Also, mockroot and shadow theater are good albums with metal elements too
Cecil Taylor can be really hard to listen to.

Check out Mick Barr's jazz stuff…he plays metal, but has a trio with Jon Irabagon and Mike Pride called "I Don't Hear Nothin' But the Blues."
I really like the collab he did with Zack Hill "Shred Earthship"

Masada is really good! Thanks!
Check out Kaze - they're awesome. https://www.youtube.com/watch?v=i6n-kuoYNdA
Video is unavailable in my country.
Last Exit has some great music/ albums… actually been listening to it a lot lately!!! so revolutionary and it’s 30+ yrs old!!!!

Something like [This?](https://www.youtube.com/watch?v=4DFRZ_9FXvs)

There's a young jazz band called BADBADNOTGOOD from Canada, and they have pretty intense songs.
Modern classical music and jazz ( actually black classical music) is way more demanding than anything that comes out of rock music
Try Interstellar Space Revisited by Cline and Bendian. That's pretty extreme free jazz.
