Doc Watson, the legendary folk and bluegrass musician whose career spanned seven decades, died at the age of 89 on Tuesday. He’ll be remembered for his talent in country, blues and folk, his founding of the MerleFest music festival, and for his influence on dozens of other prominent musicians.

Wrote Terence McArdle in Watson’s obituary:

“He is single-handedly responsible for the extraordinary increase in acoustic flat-picking and finger-picking guitar performance,” the late Ralph Rinzler, an influential folklorist who first recorded Mr. Watson in the early 1960s, once wrote. “His flat-picking style has no precedent in earlier country music history.”

Mr. Watson’s repertoire included country songs, blues and contemporary folk by writers including Bob Dylan and Tom Paxton. And he was musically adventurous, once even jamming on his flat-top folk guitar with the electric soul band Booker T. and the MGs during a 1996 performance at the Wolf Trap outdoor theater in Vienna.

Watson will also be remembered through a 1988 Washington Post profile , which said, “When Doc’s pleased, he’ll lean his head back a bit and unfurl a grin that could charm a possum out of a tree. The look on his face when he knows everything is right is ecstatic.”
