Very few musicians for the last 50 years has 'made' their own music then. Just about every last one of them has a 'producer', and from what the musicians played (most of the time, for solo acts, the producer hires who plays with them), the producer 'assembles' a hit recording (or not, depending on the producer!).
Tell me who does it ALL nowadays? Or any time?
The list of self produced great albums is pretty short.
Take Quincy Jones... Are you saying, because he didn't PLAY it all, or sing it all, that he's less of a monster for making those great albums?
Maybe you need to read their bio
