Good job. I'm the one who put the not-neutral tag and I think it is fair to remove it. I was thinking of taking a stab at "neutralizing" the entry but your revision is fine. 

By the way, even though I flagged this article as biased, I think it is a pretty good article. I read his books/bought his albums and read the Cornerstone articles. For people like me, this is a great "Oh yeah... THAT guy. Whatever happened to him?" article.
