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.
Those guys are clearly from the early 70s. I mean look at that bassist! Those type had faded away by mid 80s at the latest.
These guys are not proof of modern day talent.
They are proof of time travel.
