Mozart. Dude would be social media famous in .2 seconds. He’d be annoying us all. He’d be covering all new songs same day after hearing it once. And I’m here for that chaos.

Freddy Mercury.

Or David Bowie

Freddy Mercury

Fkn Jimmy Hendrix

Chris Cornell

Jeff Buckley, no question. He released arguably the best album of the 90s (Grace) then went and fucking drowned. Only 30 years old. He coulda been one of the best to ever do it, but we're left wondering.

Gotta go with chester, assuming you can bring them back with their health (mental and physical) "fixed" to a good massive balance.

Not because he's any better than any of the other greats that have died. Not even the ones that killed themselves.

Just because there's something about his death that makes his life feel more unfinished.

Out of any of the people listed here, I think he had the most undone. Not even in the musical sense alone, across the board.

Nirvana(Curt Cobain), Linkin Park(Chester Bennington)

Chester without a doubt.

My vote goes for J.S. Bach. One of my shower thoughts is that he would make a great experimental IDM artist. He would give Authechre a run for their money.

Imo, unfortunately, bringing back Legends will just harm their legacy (I'm thinking of John Lennon, Jimi Hendrix, David Bowie...).
However Tupac may have had an enormous impact in the 90s and early 90s music, and so on.
And who knows how grunge could have gained other mainstream success with Cobain...

Otis Redding. I didn't realize until recently that he died so young, I would've loved to see how the rest of his career turned out. His voice had such a special quality.

Peter Steele. Although he might disagree. Type O Negative's last album before his death was named "Dead again", and a lot of their music is about escaping yourself (aka suicide or extreme self harm)

Harry Chapin

Or

Karen Carpenter

(I know, they're kinda sappy but they were on my Playlist when I was young and in love.)

Wayne Static.

The first ancient cavedweller to stretch skin over a frame and start hitting it to make noises. Give Grog a full drumset and see what he comes up with

Dimebag Darrell.

We could really use a Pete Seeger or a Woody Guthrie in times like these.

Buddy Holly, Ritchie Valens, and "The Big Bopper" J. P. Richardson

Would have liked to see what would have happened if they had continued making music.

Randy Rhoads

Aaliyah. 22 is far too young to have died, and her career was moving in the craziest direction. She was set to collaborate with Trent Reznor; I wanna see how she would've changed the game.

Ian Curtis (Joy Division), though that would probably screw up the timeline for New Order and all of 80's music (not a dealbreaker).

Prince (obvs)

Petri Walli.

Really, it's a friggin' miracle that Jeff Mangum only quit and fucked off for a decade. What all musicians need to know is that success won't fix depression.

Doom.

I'd be hesitant to bring back anyone who's reason for death was suicide or substance abuse, it just seems cruel.

Stevie Ray Vaughan

Jimi hands down

John Lennon

Seriously, so many great suggestions from other people.

I'm going to throw out Neil Peart, although I'm not sure he'd appreciate it. Selfishly, I'd love to have him back.

Johann Pachelbel. So many modern songs reuse the melody from his Canon in D. I just think, it'd be fun to let him listen to them. Would probably blow his mind to listen to modern music, to begin with, and then to have it be his melody, too. 🙃

Bradley Nowell. Sublime was so good, and none of the bands that have followed in their style have had the same lyricism that Nowell had, or have been able to really blend genres like they did to make something completely unique.

Hendrix, Rory Gallagher and SRV. Imagine what the blues and the world would be like with those 3 big hitters still around.

Orpheus. I bet he’d do great fronting a metal band.

Easy: Duke Ellington
