Most Influential American Musician of All Time?


Who do you regard as the most influential (i.e., musically, not necessarily commercially) American musician of all time across all genres?

The more I learn about Louis Armstrong, the more I am persuaded that he deserves that honor.

Miles Davis, Robert Johnson, Duke Ellington, Louis Armstrong, Irving Berlin, George Gerswin, and Elvis Presley, in no particular order.

The question itself is subjective, and therefore has to definitive answer.

Cheers,

Elvis was a very good singer, a poor to fair guitarist, barely a songwriter, and a mediocre (benefit of the doubt on this one) actor.

He was a great entertainer but hardly a musician.
