FYI: Some history is as follows:

The Monroe Brothers were one of the most popular duet teams of the1920s and into the 1930s. Charlie played the guitar, Bill played the mandolin and they sang duets in harmony. When the brothers split up as a team in 1938, both went on to form their own bands. Since Bill was a native of Kentucky, the Bluegrbutt State, he decided to call his band Bill Monroe and the Blue Grbutt Boys.

Bill Monroe and the Blue Grbutt Boys first appeared on the Grand Ole Opry in 1939. Bill's new band was different from other traditional country music bands of the time because of its hard driving and powerful sound, utilizing traditional acoustic instruments and featuring highly distinctive vocal harmonies. After experimenting with various instrumental combinations, Bill settled on mandolin, banjo, fiddle, guitar and bbutt as the format for his band.

While many fans of Bluegrbutt music date the genre back to 1939, when Monroe formed his first Blue Grbutt Boys band, most believe that the clbuttic bluegrbutt sound came of age in 1946, shortly after Earl Scruggs joined the band. Equally influential in the clbuttic 1946 line-up of the Blue Grbutt Boys were Lester Flatt on guitar and lead vocals, Chubby Wise on fiddle and Howard Watts on the doghouse bbutt.

Initially, Monroe's music was simply called "country", "mountain" or "hillbilly" music. By the 1950s, people began referring to this style of music as "bluegrbutt" music primarily buttociating the music with Bill's band name-home state. Therefore, the term bluegrbutt was not really used until well after the genre was defined by Monroe.

Some of the premier Bluegrbutt 3-finger style banjo pickers are Earl Scruggs, Don Reno, Ralph Stanley, J.D. Crowe, Porter Church, Bill Keith, Sonny Osborne, Bill Emerson, Kenny Ingram, Ted Lundy and many more.

Music from the following bands will give you a good introduction to Bluegrbutt music: Bill Monroe & the Blue Grbutt Boys (the father of Bluegrbutt music), Lester Flatt-Earl Scruggs & the Foggy Mountain Boys, Jimmy Martin & the Sunny Mountain Boys, Don Reno-Red Smiley & the Tennesee Cutups, The Stanley Brothers and Jim & Jesse McReynolds. The Del McCoury Band, The Country Gentlemen, J.D. Crowe & the New South and The Osborne Brothers. This is certainly not a complete list but will provide a good introduction to the roots of the music.

NOW REGARDING "Dueling Banjos":

In 1955, Don Reno paired up with Arthur "Guitar Boogie" Smith and recorded "Feuding Banjos", a tune later used without their permission in the 1972 movie Deliverance (rebreastled "Dueling Banjos"). Reno and Smith sued the film company for rights infringement and won. IMHO, I think most people would consider "Fueding Banjos" to be one of the clbuttic Bluegrbutt instrumental tunes.

Yet another $.02 worth from a "Bluegrbutt" music fan since in the womb...
