Honorable Mention......

^^ Yeah, Neurosis is really cool, good thing they are still releasing good albums

THe best band I've heared in a long time is Maudlin of the Well (that later changed into Kayo Dot), a nice band with doom/death meta, Jazz, prog-rock, etc influences
 
^^ You got that right Kev.

So, there are a few bands/albums I've discovered recently:

Hurt - Vol.1 : Just wow, I can't believe this is their debut album cause the sound of the band is so polished, it has some obvious Tool/APC influences, I can hear some dredg too and some grunge influences

Across Tundras - Dark Songs of the Prairie : This band mixes a sludge Cult of Luna/Isis/Pelican sound with some Psychodelic rock elements, it's really cool but I still have to give it a few more spins

Bubu - Anabelas : This is an Argentinian 1970's band and as you can guess it's prog rock in the veins of King Crimson (Red era) and Magma
 
I found some new and nice bands too..
Few to name SikTh, Boris and Sunn O))).

And the I found Metsatöll (Estonian folkmetal). It was kinda surprise,
because I'm not so keen on folkmetal. Also Drudkh was something new to me.

And few ambient-discoverys to name; Troum (German dark ambient)
and The 4th Floor from Finland.
