In general, Parliament/Funkadelic has a ton of artists within its scope worth exploring. George Clinton is probably the most famous among them, but there's also Eddie Hazel, Bootsy Collins, Gary Shider and his son Garrett Shider, Fred Wesley, and a lot more.
I also recently discovered a Japanese artist called Masaki Ueda who seems criminally unknown.
The P-Funk has been in my playlist rotation for like 15 years now
Jukebox the ghost. Criminally underrated, they'd have been as big as queen or muse if they had the right publicity and timing.
The Tallest Man on Earth. Probably the best modern folk artist, but not as well known as he should be.
Aimee Mann. One of the best songwriters of the 90s and 2000s. Popular, but not as much as she should be.
Placebo.
Talk Talk. Spirit of Eden is one of the greatest albums ever made, but not many people know about it.
Tallest man is really good. And if you see him live, his tallness will surprise you.
Nick Drake.
Years ahead of his time and while he gets a lot of recognition posthumously in certain music circles, he didn't have any hits during his life, or even any hits after, so the average Joe hasn't heard of him.
All three of his albums are fantastic, though Five Leaves Left is my favorite.
Evade the Eye. Excellent guitar work, good songwriting. Genre: instrumental prog metal
TOBACCO has this super-sludgy techno sound that next to no one's doing; I love his work for just kicking back and lighting off a blunt. Been pretty heavy on American Murder Story as well, since it looks like we're not getting the finale to the Devil's Carnival yet.
TOBACCO is one of my lifelong top artists - his work with Black Moth Super Rainbow is great as well.
In my opinion Malibu Ken is his best project though, it's one of my all time favourite albums. Aesop is on another level
When Malibu Ken dropped I think I looped that album for a solid month. Been listening to Aes for years now; sometimes, I need my bars esoteric and bout as dense as an elephant's foot
Nineteen Forty-Five
Their debut album, Together We'll Burn Like Autumn Leaves is solid gold all the way through; the second studio album I Saw a Bright Light is almost as solid. I like them so much I tracked down all the members' previous bands and solo projects and B-sides.
BONES/ Surrender Dorothy. he's gained a lot more listeners over the past few years so more people are discovering his music
Emma Ruth Rundle
TR/ST
Ionnalee
Keosz
Rival Consoles
I Will Keep Your Ghost
Moon Cathedral
Russian Circles
Panpticon, King Gizzard and the Lizard Wizard, Chat Pile, Ashenspire, Swans, Obongjayar, Black Midi, and emancipator
Jason Molina, particularly his last act, "Songs: Ohia". Singer, songwriter, sad bastard indie rock artist who died in his early thirties from complications of alcoholism. Like Will Oldham with more bluesy pop influences instead of bluegrass and folk.
