“what’s new”
there’s a whole industry (shed concerts with $45 general admission hillside seats, $150 covered seats; “classic rock radio”; programming for film soundtracks and commercials) invested in seeing their “big hit” rock properties of old returning residual money.
It can be argued that Led Zeppelin and Rolling Stones were big acts that won’t be replicated.
Don’t understand the big event draw and radio presence of Foreigner today. Corporate rock of the 70s is still corporate rock of 2018.
