I want to know the answer to the following question:
What technique did Jesse McReynolds create?
All the background I'm provided with is that "The late John Duffey of the original Country Gentlemen and later the Seldom Scene did much to popularize the bluegrass mandolin among folk and urban audiences, especially on the east coast and in the Washington, D.C. area.". Is that enough to answer the question?
Answer: no
