These festivals with legacy acts are almost exclusively filled with an older audience. There are hardly any people my age or younger.
Add to that, these festivals rarely have a combination of young and older talent, because the former would be severely exposed. Who are The Isley Brothers, Kool & The Gang, Boyz 2 Men, Aretha Franklin, Whitney Houstons of today?
How many of this generation receive formal vocal training in the church? Can play instruments? Understand scales, chord progressions, modes? Digital producing and a lack of musical school funding destroyed all that.
A rapper who can barely string a sentence together can build a whole career from soundcloud, fruity loops and TikTok.
If you put them on the same stage as this generation’s stars, the gulf in talent would be severely noticeable. I could be wrong but I don’t think there is a festival which has an equal amount of young and new talent on the same stage, because the disconnect would be too great.
Just like we saw with Method Man and Red Man in the OP’s article.
