Iconic guitarist Doc Watson in critical condition

Seven-time Grammy-winning guitarist and singer Doc Watson, flatpicking master and founder of the annual MerleFest, is in critical condition in a North Carolina hospital.

The 85-year-old singer/songwriter, whose real name is Arthel, is being hospitalized at Wake Forest Baptist Medical Center after a fall in his Deep Gap home earlier this week, according to the Winston-Salem Journal.

Watson's daughter Nancy revealed that the performer fell Monday and didn't break any bones, though he's "real sick," according to a telephone interview with the newspaper.

The bluegrass/folk musician has released more than 20 studio and live albums, including his most recent effort, the three-disc "Legacy." The 2002 collection, which features rare photographs, interviews and a live show, won the Grammy Award for Best Traditional Folk Album.

Watson founded MerleFest, one of the nation's leading acoustic festivals, in 1988. The four-day event is named after Watson's late son, Eddy Merle Watson, who died in a tractor accident on the family farm in 1985. Doc Watson performed at the event just last month, as he's done every year of the 25-year festival.
