If you could bring back one great artist that has

GEORGE CARLIN deserves to come back as no one else in this world. Forget JC, he'll come back on his own LOL

I'll respond only for popular music and leave the classical to the more informed than me.

The most tragic and biggest loss is John Lennon, hands down.
But he had already made his mark before he died, and despite whatever wonderful music we missed out on because of this untimely death at age 40, his best work was surely behind him.

So from the standpoint of who we lost at the peak or upswing of their career, I'll go with Buddy Holly overall (though before I was born I'm aware of his impact). And from a musician standpoint, Duane Allman. So much brilliant music never got made...

Abrew19, unfortunately John Lennon is the last one I want to bring back if I got the chance. I believe he's got what he deserved as payback for his brutality, violence and ignorance.

Czarivey what are you smoking?

speaking of ignorance....
