Please reccomend me slam

Looking for bands that have kind of a specific set of parameters.

I like slam metal that has pretty good production value, I like to be able to discern the guitar riffs.

I like stuff that grooves really well, especially during some kind of breakdown that contrasts with most of the song, with notable beat changes throughout the song. I don't really like stuff thats essentially just one long breakdown, even though I know that's a lot of slam these days.

I also know that the production value of slam may be limited somewhat by just low funding overall.

Bands i like, pathology, abominable putridity, extermination dismembermemt, dysentery, dying fetus, some devourment, guttural slug, etc..

And feel free to list bands that might be described as "basic" slam. Assume i know nothing about the genre.
