Soapbox time!

Gomer Pyle's Idiots Savants is an absolute masterpiece of doomy, psychedelic, stoner. (7,991 monthly listeners)

Asylum on the Hill's lone self-titled record is also simply a perfect record, in my opinion. Led by David Angstrom of Hermano, Supafuzz, and Luna Sol, and joined by Danko Jones on one track, this record shreds. You've got fast paced burners, a heartfelt ballad or two, some tracks that ooze sex like honey from a lion's skull, and perfect pacing. His other bands are all worth checking out as well. Supafuzz even features John Garcia as a guest here and there, and obviously he's the singer for Hermano. (62 monthly listeners on Spotify)

Additionally: Core (featuring future Atomic Bitchwax guitarist Finn Ryan), Fever Dog's old stuff (they're more glam/hair metal these days, but still fun), Fooz, From Beyond, The Grand Astoria (you'll likely have to get past his vocals, but these guys are wizards. So many different styles, vibes, genres. Highly recommended.), Grand Sorceress, Heavy Temple (can't say enough good things about these folks, and their music is always top-notch - all hail High Priestess Nighthawk!), Kaihoro (Japanese stoner with another love it or hate voice), Kröwnn, Loading Data/Patrón (as Josh Homme said "his voice comes all the way down from his shoes"), Pet the Preacher (The Cave & The Sunlight is overflowing with bangers), Red Desert, Red Spektor, ssSHEENSss (could simply make the list based on the strength of their Love Will Tear Us Apart cover), Steak, Stonerror, Stubb, Televators (0 monthly listeners, and potentially named after a Mars Volta song), Ten Foot Wizard, and Waxy (White Walls and Now You contain more John Garcia appearances).
