In past you had to have musical talent to become a musician. People would come to watch the artist create the music.
Today the only requirement is a pretty face, or slick image. The studio could make my cat a rockstar.
Because of that many 'live' shows are now pre-recorded, or just shit.
Great musicians busk for coins in the subway, while untalented hacks, with big racks, collect all the rewards from media.
Honestly, the vast majority of bands I listen to sound better or as good live, though I guess that's just a quality that punk and other genres have.
