Yes, unfortunately, what happened was what is called a WP:Close paraphrase, something that was present in some of the other rewrites I have reviewed those past days, but here to an extent where it was not directly fixable by myself.
I chose to remove the entire career section but still restore the rest because the lead + discography were building a viable stub, which BTW contains every single reference present at the time of the review. I'll be looking in the full copyvio version to see if there is anything else and port it back into the article when I have a moment.

As I expect  will confirm, close paraphrasing is where copyright laws become really tough to comply with, and I sympathize with the difficulty this presents. Nonetheless, I cannot, for obvious reasons, restore the text of the career section, as any modification of that would constitute an unauthorized derivative. And of course, I appreciate that the fact that only admins can verify my statement makes it doubly difficult. That being said, I'd welcome a second look from Frank or MRG if this is desirable.
