It's been awhile since I've found new metal music that I've really enjoyed, and these days, I splurge a lot more into other genres. That said, I figured it would be worthwhile to post here and see if anything you guys suggest sparks some new life into my inner metalhead.

Looking in particular for long songs (>10 minutes) with a trudging groove, as I like the atmosphere to build and build. Folky elements are welcome, too. The bands I listen to most are Agalloch, YOB and Summoning. Perhaps lesser known, but I also really enjoy Midnight Odyssey, Ne Obliviscaris and Gallowbraid.

Thanks a bunch!

This should be what you're looking for.

Possibly Dark Buddha Rising?

In terms of folky bands post-Agalloch (I'm a huge fan myself), I'd check out Alda.

You have a pretty diverse tastes of bands that dont quite mix well with each other. Im not a good sludge fan but I do understand summoning, midnight odyssey, and ne obliviscaris. Most of my complaint agains sludge metal is it lacks the theatrical and more rich atmospheric elements of those 3 groups i pointed out.

A band I can think of is GOATPSALM "Downstream" I cant remember how long their songs were but I remember they had a weird folk/sludge combo that seemed interesting. https://www.youtube.com/watch?v=9_0-QJ9IjpY

I mean... have you heard of ESOTERIC? I think most everyone knows of that group. If you havent, then youre definitely need to try them out. https://www.youtube.com/watch?v=3jo0Pz5SmXs


Also on a side note.... this cannot go without mention, but what about Locus Requiescat for insanely absurdly long funeral death doom stuff https://www.youtube.com/watch?v=gyT1fck ... 6Q37t_tfeQ
