The Foggy Mountain Boys was an American bluegrass band. The band was founded by guitarist Lester Flatt and banjo player Earl Scruggs and is viewed by music historians as one of the premier bluegrass groups in the history of the genre. The band was originally formed in 1948 by Flatt, who had been a member of Bill Monroe's bluegrass band. Flatt brought Scruggs with him shortly after leaving Monroe.
