It's safe to assume that many artists will peak in their artistic lives, then afterwards they slowly descend and are never able to match the amazingness that was their peak. Some receive moderate success afterwards, some even get rivaled success compared to their best, and some pretty much flop off the face of the charts. When was your fave's peak?
Monumental album?
Singles reign?
Blockbuster performance?
Chart domination?
