William Smith Monroe, famous as Bill Monroe, was an American musician who created a sub-genre of Country music known as the ‘Bluegrass music’ which gained much support and love in urban areas already flooded with the country music, encountering occasional pop tides. Bill described his music as ‘Scottish bagpipes and ole-time fiddlin’, which inspired many generations of musicians. He played a key role in folk music revival and revolutionized the music style of that time by mixing elements of old-time string bands with the blues, rural spiritual singing, and jazz solos. Bill had acquired the 1923 Gibson F5 model "Lloyd Loar" mandolin which became his trademark instrument for his career. He is also credited to have brought mandolin to the forefront, where only fiddle dominated. He defined the sound and style of classic bluegrass - a five-piece acoustic string band playing precisely and rapidly, switching to solos and singing in a high-pitched, gospel tinged voice. His signature song, ‘Blue Moon of Kentucky’, went on to become the official bluegrass song of Kentucky. He returned to the Billboard’s chart posthumously in 2005 with the compilation ‘Bill Monroe and His Blue Grass Boys: The Definitive Collection’. His tight, crisp, string-band sound is enjoyed all across Europe, America and Japan.
