The fact for real is not at all in all the beauty of classical music, but in the appreciation factor.
Nowdays only small group of educated people would enjoy listening to music vs. pop fake whilist past times not to long ago it had substantially larger magnitude.
Becides classical there was jazz, sophisticated rock bands, neo-classical performers and composers, brittish envasion, progressive rock, 60's,70's,80's, some 90's and than sudden lapse... Northern Europe is still having substantially larger group of music appreciation than the rest of the world.
Will we ever have another rock band that would book venues larger than bar stage or even the bar stage will be too large for the skillfull rock band? That would be realy sad.
