Haven't delved into music in the latter half of the decade nearly as much as before, but here's my list:
Bell Witch: Usually not super into funeral doom, but these guys hit the right notes.
Chelsea Wolfe: She peaked with Pain Is Beauty in my opinion. Marvelous record, great live show.
Cloud Rat: Relentless. Moksha is out of this world. Saw them play in a damp cellar with terrible sound.
Colleen Green: Sock It to Me has some bangers that are still on heavy rotation.
Demdike Stare: They absolutely slaughtered 2010 with three fantastic records, but petered out a bit after that for me.
Khruangbin: It's mellow, yeah, but I dig their sound, including Mordechai.
Kikagaku Moyo: These guys as well, awesome psyche. Fantastic live.
Masakari: They disappeared as quickly as they emerged, but The Prophet Feeds follows the perfect crust punk formula for anyone into His Hero Is Gone, From Ashes Rise etc.
Pallbearer: Hard to beat Sorrow and Extinction and Foundations of Burden as far as trad doom goes. Shame the last one was a dud. Decent show, but the vocals were a bit weak.
Power Trip: Nightmare Logic was massive for me. RIP Riley Gayle. Missed them on tour, fml.
Raime: When everyone was going bananas over Andy Stott, Quarter Turns Over a Living Line was my jam.
Waxahatchee: Nothing after American Weekend really grabbed me, but I adore that record.
Windhand: Brilliant riffs and sweet sound, which they nail live as well.
I guess some of those would make up around half of an imaginary top 10/20 of the decade list, the other half being more established artists. And as I said, mostly focused on the early 2010s records.
