There are still 1-2 generations left who "fullfill" all their GAS they could not when they were 17 or even 25..take a look around you and tell me how many young lads have the same fanatism for learning a instrument like guitar or drums like they spend their time for "doing" hiphop,Dj orwhatever other "sport" a young guy right now can do for "expressing himself" without to sit down and spending many hours of practicing guitar every day.
Well, I guess I have different impressions.
I see a surprising number of young musicians with a high level of education and greater skill in my immediate surroundings.
In the nearby city there is a university for classical music and jazz as well as seminars for rock and pop music and it is difficult to get a study place.
About thirty years ago it was easy for me to enrol 2 semester as an extraordinary student for theory subjects. Now it would be impossible.
So for me, the musical level of the armateur (and professional) musicians surrounding me has risen enormously in the last decades.
I was described as a good armature guitarist in my younger years, I don't get along with this guy's anymore.
Of course, there are also the pure consumers (the possibilities for this are now enormous) but that was not different in our time.
