Rock and Roll as it was in the 60s and 70s is long dead. Similar to what happened by the end of the 60s/70s with young people and hot rods...Now all ya see are gray haired old guys driving 100k++ rods or high end cars on holidays..
Most young people have no interest, or the big bucks to get involved in that game today.
The arena rock/stadium rock/corporate rock era was actually short blip in the history of music and it came courtesy of Bill Graham. The bands still playing the sheds today are the ones that played the stadiums in the 70s and 80s and they play to the same audiences.
