Fleetwood Mac are a British-American rock band formed in July 1967, in London. The band have sold more than 100 million records worldwide, making them one of the best-selling bands of all time. In 1998, selected members of Fleetwood Mac were inducted into the Rock and Roll Hall of Fame, and received the Brit Award for Outstanding Contribution to Music.

The two most successful periods for the band were during the late 1960s British blues boom, when they were led by guitarist Peter Green and achieved a UK number one with "Albatross"; and from 1975 to 1987, as a more pop-oriented act, featuring Christine McVie, Lindsey Buckingham and Stevie Nicks. Fleetwood Mac's second album after the incorporation of Buckingham and Nicks, 1977's Rumours, produced four U.S. Top 10 singles (including Nicks' song "Dreams"), and remained at No. 1 on the American albums chart for 31 weeks, as well as reaching the top spot in various countries around the world. To date, the album has sold over 40 million copies worldwide, making it the eighth-highest-selling album of all time.

The band achieved more modest success between 1971 and 1974, when the line-up included Bob Welch, during the 1990s in between the departure and return of Nicks and Buckingham, and during the 2000s between the departure and return of Christine McVie.

Due to numerous lineup changes, the only original member present in the band is drummer Mick Fleetwood. Although band founder Green named the group by combining the surnames of two of his former bandmates (Fleetwood and McVie) from John Mayall's Bluesbreakers, bassist John McVie played neither on their first single nor at their first concerts, as he initially decided to stay with Mayall. Keyboardist Christine McVie, who joined the band in 1970 while married to John McVie, has appeared on every album except the debut album, either as a member or as a session musician. She left the band in 1998 but returned in 2014.

Otis Spann (March 21, 1930 – April 24, 1970) was an American blues musician, whom many consider to be the leading postwar Chicago blues pianist.

William James Dixon (July 1, 1915 – January 29, 1992) was an American blues musician, vocalist, songwriter, arranger and record producer. He was proficient in playing both the upright bass and the guitar, and sang with a distinctive voice, but he is perhaps best known as one of the most prolific songwriters of his time. Next to Muddy Waters, Dixon is recognized as the most influential person in shaping the post–World War II sound of the Chicago blues.

Dixon's songs have been recorded by countless musicians in many genres as well as by various ensembles in which he participated. A short list of his most famous compositions includes "Hoochie Coochie Man", "I Just Want to Make Love to You", "Little Red Rooster", "My Babe", "Spoonful", and "You Can't Judge a Book by the Cover". These songs were written during the peak years of Chess Records, from 1950 to 1965, and were performed by Muddy Waters, Howlin' Wolf, Little Walter, and Bo Diddley; they influenced a generation of musicians worldwide.

Dixon was an important link between the blues and rock and roll, working with Chuck Berry and Bo Diddley in the late 1950s. His songs have been covered by some of the most successful musicians of the past sixty years including Bob Dylan and Jimi Hendrix. Jeff Beck, Cream, The Doors, Led Zeppelin, The Rolling Stones and Steppenwolf all featured at least one of his songs on their debut albums, a measure of his influence on rock music.

He received a Grammy Award and was inducted into the Blues Hall of Fame, the Rock and Roll Hall of Fame, and the Songwriters Hall of Fame.
