Yannis Papadopoulos of Beast in Black. Dude's got some insane vocal range.

Nobody will read this, but Kristin Hersh. She was the founder / less singer in Throwing Muses, but her solo work truly amazes me. Literally nobody is like Kristin.

For example: https://piped.video/watch?v=_RtniRWL5zM

Michael Buble

Rory Rodriguez of Day Seeker

Haley Williams of Paramore

There is something captivating about Kate Bush's delivery, she collaborated a lot with Peter Gabriel too who was a fantastic singer with unique delivery as well.

Linda Perry.

Lead singer of 4 Non Blondes and has a solo career. I don’t even listen to that style of music, but I still get excited when I hear her voice come on.

Why don't we ask Lemmy?

Ronnie James Dio.

Does Jack Stauber count? The songs I've heard from him are mind blowing

Pavarotti. Goosebumps. every. time.

Whoever this is

tldw; a contestant on a European pop idol type show had such perfect pitch and tone, the judges thought she was lip syncing. She wasn't and it's amazing.

Milli Vanilli.

Jim Grey of Caligulas Horse and Arcane

And Devin Townsend

I'm consistently impressed by the one vocalist from Beast in Black. When I watch their videos and then realize there is one voice in the song and it's that dude, it blows my mind every time.

Michael Akerfeldt

Gives me chills every time he sings for the past 20 years.

Amber Bain of The Japanese House has a really nice voice.

There's also Caroline Polachek, who I am pretty sure actually has perfect pitch. She is one of the most technically impressive vocalists of her generation IMO.

Adam Lambert.

Holy fuck his range and control. It’s insane.

Even if his music is mediocre, his vocals are amazing.

Brody Dalle gives me chills every time

Andy Hull from Manchester Orchestra

Einar Solberg, lead singer of Leprous, has a unique voice. It can sound almost fragile at lower registers, very expressive.... And has incredible range.

Alleviate

Vitas.

Brandi Carlisle is completely wasted on country music. I saw her at a music festival when she was mostly playing rock music and some covers and holy shit she has such effortless range.

Vessel from Sleep Token

Saw her play live recently. She's still got it.

Hildegard von Blingin’ sings like an angel: https://www.youtube.com/@Hildegardvonblingin/videos
