Most Influential American Musician of All Time?

There is no 'greatest'.

There are people who define an era or particular kind of music.

Analogtroll beat me to the naming of one: Woodrow Wilson (Woody) Guthrie.

Then, of course there are the big-time commercial successes like Bernstien and Gershwin and Armstrong.

Someone mentioned the Beatles...which are, of course one of many British Bands that introduced White America to The Blues.

Thank you, everybody for leaving Irving Berlin out of it.

Ah, let the controversy roll....(and rock!)

Tvad, Yes David Cassidy is right up there with Bobby Sherman and Frankie Avalon.

All of which, I am sure, broke Annette's heart.....
