2. Constant Paranoia (Holland) "Spirals II Infinity" (2004)
This is great stuff, a mixture of technical and progressive death metal. Very eventful compositions full of addictive riffs and interesting time and tempo-changes.

Also make sure to check out their new album "Take the Fall" (2013), another excellent piece of technicality. By the way, both their albums and the demo can be downloaded from their website in the form of youtube files.

3. Klast (USA) "Tropean Winds" (2012)
Surreal dissonant riffs played slowly to mid-pace; very depressive, but utterly original stuff: think the last Ulcerate album, but this is better. If Portal were playing much more slowly, this is how they would have sounded.

4. Catarrhal (Belgium) "Putrescence" (2007)
Very inventive original music; the guys change the riff-paterns and the pace the whole time also adding melodic progressive elements ala Theory in Practice. At times too complex, at times simply beautiful.

Their new opus, "Fleshgrave" (2013), is another good work, but clings more towards the progressive and the atmospheric; the technical riffage is missing at times

5. Arkhe (Mexico) "Virtual Landscape" (2005)
This is pretty much Atheist minus the speed. If "Unquestionable Presence" was too brutal for you at times, this is the album you should get immediately. At times it's probably too peaceful bordering on thrash, but it's very stylish music all the way.
Their new album, "Spirals of Life" (2013), is another great album, very similar to this one.

6. Subconscious Terror (Japan) "Invisible" (1996)
This is an old album, that's why it's a shame that it's so largely forgotten. Long compositions where a lot of things happen, probably more on the progressive side, but very interesting music all the way.

7. Exuviate (USA) "Exuviate" (2000)
This is not for everyone: ultra-brutal very fast stuff and extremely technical at the same time. There are slower slamming breaks incorporated as well as dissonant abstract riffs ala Ulcerate and Portal again, including a great schizophrenic instrumental caled "Insanity" which is truly "insanity", one of the highest achievements in the genre. You'll be shocked to find out that the vocalist is a woman...

8. Dichotic "Collapse into Despair" (1998)
This is a must-have for fans of very stylish weird music. Very complex stuff with some of the most original decisions you can come across on the whole scene.
Their 2nd album is too abstract, not very easy to follow, but is another recommended listen.

9. Grotesque (Australia) "Museum of Human Disease"
The Asutralian answer to Necrophagist; short tracks packed with thousands of riffs. There is a certain feeling of a show-off, of course, but this is too good to be ignored.

10. Neuroma (UK) "Extremophile" (2011)
Melodic technical death metal bordering on the progressive; not always very fast, but utterly engaging and very cleverly executed.


And here are a few more bands whose all work can be checked:

Bloody Sign (France)
These guys are viewed as a black metal band, but their style is pretty much technical death metal, and very good one at that. Their last album, "Chaos Echoes", is more on the dissonant abstract side, but is still worth a listen.

Bowel Stew (Italy)
This is one of the fastest playing bands in the world right now. Their music certainly borders on grindcore at times, but it's quite technical which can't be noticed at first since the band play super-fast the whole time.

SikFuk (USA)
This band is quite popular so I believe most of you know it. Still, since it reminds me so much of mid-period Carcass (think "Necrotism...", above all) I can't help but highly recommend each of their three albums which are full of sudden tempo-changes and some really sick twisted riffs.
