I prefer producers that are more transparent in capturing the artist.
Unfortunately some producers imprint more of themselves on an artist than I like.
That being said, sometimes the paucity of material submitted along with how ambitious the artist is, can sometimes leave gaps that inevitably the producer instead of the artist fills.
All Things Must Pass, George Harrison is a perfect example. George was pleased with the album as was the public. Later releases, especially with Jeff Lynne producing, seemed to exhibit the same gaps which the producer filled in their signature manner. Again, Harrison was pleased. That is what leads me to believe George was a little lazy.
I always wished, someone would have said, "yeah you "used" to be a Beatle, how about working a little harder and finishing this stuff yourself". But, I'm guessing you would have to not be enamored by the man, to push that opinion.
I find myself wondering what exactly the producers do with Dylan as his elocution is much better on recordings yet many of his tours find me wondering what the hell is he playing, only to find out it's a well known tune.
With that being said, touring for fifty plus years, with his catalog, it would be impossible for me not to retool a tune here and there, which would no doubt drive the fans nuts, but at least make me not hate performing the tune, which would most likely be noticeable and a bigger detriment to the performance.
