Bluegrass refers to several species of grasses of the genus Poa (with the most famous being the Kentucky bluegrass)

The term has also been applied to various things that relate to the region in which the grass grows:

Earl Eugene Scruggs (January 6, 1924 – March 28, 2012) was an American musician noted for perfecting and popularizing a three-finger banjo-picking style (now called "Scruggs style") that is a defining characteristic of bluegrass music. Although other musicians had played in three-finger style before him, Scruggs shot to prominence when he was hired by Bill Monroe to fill the banjo slot in his group, the Blue Grass Boys.

Scruggs was born near Shelby, Cleveland County, North Carolina, to Georgia Lula Ruppe and George Elam Scruggs, a farmer and bookkeeper, who played banjo and died when Scruggs was four years old. His older brothers, Junie and Horace, plus his two older sisters, Eula Mae and Ruby, all played banjo and guitar. Scruggs' mother played the organ. He grew up in Cleveland County, North Carolina.

Scruggs joined Bill Monroe's Blue Grass Boys in late 1945, and quickly popularized his syncopated, three-finger picking style. In 1948 Scruggs and guitarist Lester Flatt left Monroe's band and formed the Foggy Mountain Boys, also later known simply as Flatt and Scruggs. In 1969, they broke up, and he started a new band, the Earl Scruggs Revue, featuring several of his sons.

Richard Lee "Ricky" Skaggs (born July 18, 1954) is a country and bluegrass singer, musician, producer, and composer. He primarily plays mandolin; however, he also plays fiddle, guitar, mandocaster and banjo.

Ricky Skaggs was born in Cordell, Kentucky. He started playing music at age 5 after he was given a mandolin by his father, Hobert. At age 6, he played mandolin and sang on stage with Bill Monroe. At age 7, he appeared on television's Martha White country music variety show, playing with Lester Flatt and Earl Scruggs. He also wanted to audition for the Grand Ole Opry at that time, but was told he was too young.

In his mid-teens, Skaggs met a fellow teen prodigy, guitarist Keith Whitley, and the two started playing together with Whitley's banjoist brother Dwight on radio shows. By 1970, they had earned a spot opening for Ralph Stanley and Skaggs and Keith Whitley were thereafter invited to join Stanley's band, the Clinch Mountain Boys

Skaggs later joined The Country Gentlemen in Washington, DC, J. D. Crowe's New South. For a few years, Skaggs was a member of Emmylou Harris's Hot Band. He wrote the arrangements for Harris's 1980 bluegrass-roots album, Roses in the Snow. In addition to arranging for Harris, Skaggs sang harmony and played mandolin and fiddle in the Hot Band.

James Travis Tritt (born February 9, 1963) is an American, Grammy winning, country music singer from Marietta, Georgia. He signed to Warner Bros. Records in 1989, releasing seven studio albums and a greatest hits package for the label between then and 1999. In the 2000s, he released two albums on Columbia Records and one for the defunct Category 5 Records. Seven of his albums (counting the Greatest Hits) are certified platinum or higher by the Recording Industry Association of America (RIAA); the highest-certified is 1991's It's All About to Change, which is certified triple-platinum. Tritt has also charted more than forty times on the Hot Country Songs charts, including five number ones — "Help Me Hold On," "Anymore," "Can I Trust You with My Heart," "Foolish Pride" and "Best of Intentions" — and fifteen additional top ten singles. Tritt's musical style is defined by mainstream country and Southern rock influences.

He has received two Grammy Awards, both for Best Country Collaboration with Vocals: in 1992 for "The Whiskey Ain't Workin'," a duet with Marty Stuart, and again in 1998 for "Same Old Train", a collaboration with Stuart and nine other artists. In addition, he has received four awards from the Country Music Association, and has been a member of the Grand Ole Opry since 1992.

Vincent Grant "Vince" Gill (born April 12, 1957) is an American country singer-songwriter and multi-instrumentalist. He has achieved commercial success and fame both as frontman to the country rock band Pure Prairie League in the 1970s, and as a solo artist beginning in 1983, where his talents as a vocalist and musician have placed him in high demand as a guest vocalist, and a duet partner. Gill has recorded more than twenty studio albums, charted over forty singles on the U.S. Billboard charts as Hot Country Songs, and has sold more than 22 million albums. He has been honored by the Country Music Association with 18 CMA Awards, including two Entertainer of the Year awards and five Male Vocalist Awards. Gill has also earned 27 Grammy Awards, more than any other male Country music artist. In 2007, Gill was inducted into the Country Music Hall of Fame.

Vincent Grant "Vince" Gill was born in Norman, Oklahoma. His father, J. Stanley Gill, was a lawyer and administrative law judge who played in a country music band part time and encouraged Gill to pursue a music career. At the encouragement of his father, Gill learned to play several instruments, including the banjo and guitar, before he started high school at Oklahoma City's Northwest Classen High School. He first played with a teenage band called Bluegrass Revues in the late 1970s. The other members were: Billy Perry on the banjo, Bobby Clark on the triangle and Mike Perry on the bass.
