If you could bring back one great artist that has

Great question, just too hard for me to answer.

John Lennon..hmmm. I was listening to an old interview with his first wife a week or so ago on NPR, and for someone who promoted love and peace, it certainly seems that he didn't practice it in his own life. Yoko was even worse.
He didn't support his ex-wife or son even though he was extremely wealthy.
I never counted him among my favorite artists, but now even less so.

Jack Bruce
Jerry Garcia (just kidding)

"J.S. Bach is better than all mentioned put together !"

One man’s narrow minded opinion. All human creations are fascinating by their very nature, and each is appealing to someone. There are countless profound musical creations by many minds. You believe J.S Bach trivializes most if not all others. Good for you schubert; but that is your fiction, not actual fact.

bdp24,
I don't think you're being argumentative, and I understand that many brilliant people respect him greatly as a genius. I own several discs of his music myself. I made my comment because Schubert has demeaned other music repeatedly in the past, implying that it was without musical worth. I think that this mostly applied to the rock genre. 
My point is that even though some music composers have both amazing technical acuity in their compositions as well as the ability to evoke emotional responses from listeners, many composers and songwriters of much more humble technical abilities are able to evoke the same emotional responses, and it is narrow minded to dismiss their work. I hope that makes my response more clear.

geoffkait and cleeds,
Thanks for your comments. You both said some things that I wanted to say, but deferred because Mr. Schubert is a senior member.
