They have saved the lives of those millions of children by keeping their interests out of gangs, drugs, and violence.

Do you want silent movies? No? Then maybe if you paid attention you’d see that symphonic groups and big bands are used in movies.

How can you call any art form dead just because it’s not “mainstream”?
Is painting dead because that’s not popular?
Sculpting?
Would you call THOSE art forms dead? I don’t think so.
Get your head out of your ass.
