Steve Martin, writing in The New Yorker earlier this year:
As boys in the little community of Flint Hill, near Shelby, North Carolina, Earl and his brother Horace would take their banjo and guitar and start playing on the porch, then split up and meet behind the house. Their goal was to still be on the beat when they rejoined at the back. Momentously, when he was ten years old, after a fight with his brother, he was playing his banjo to calm his mind. He was practicing the standard “Reuben” when found he could incorporate his third finger into the picking of his right hand, instead of his usual two, in an unbroken, rolling, staccato. He ran back to his brother, shouting, “I’ve got it, I’ve got it!” He was on the way to creating an entirely new way of playing the banjo: Scruggs Style.
Great profile of Scruggs, who was probably the best there ever was, and maybe the best that ever will be. (Also, if you click through there’s a recording of “Foggy Mountain Breakdown” to listen to.)
