Rock ’n roll is really swing with a modern name. It began on the levees and plantations, took in folk songs, and features blues and rhythm. It's the rhythm that gets to the kids – they're starved of music they can dance to, after all those years of crooners.
When God created Man, he gave him Music as a language different from all other languages. And early man sang his glory in the wilderness; and drew the hearts of kings and moved them from their thrones.
The effect of music is so very much more powerful and penetrating than is that of the other arts, for these others speak only of the shadow, but music of the essence.
