Experienced artists. What a difference it makes. At least when music is involved.
Many of us older farts dislike of even detest "new music". For many of us it has no beat, no taste, no substance, NO SOUL.
Some younger artists have soul, but not very many. Most older musical artist do have soul, and it makes such a difference in the experience of the listener.
Older musicians have years of playing whatever instruments it is that they play, and that certainly makes a difference to the performance.
Older musical artists also love what they do, or they would be burnt out and not playing anymore.
So these mature musicians have technical expertise and enjoy performing, but that isn't the entire equation. It's life longer lived that makes the sound something worth listening to.
