Lindsey Adams Buckingham (born October 3, 1949) is an American guitarist, singer, composer and producer, most notable for being the guitarist and male lead singer of the musical group Fleetwood Mac from 1975 to 1987, and 1997 to present day. Aside from his tenure with Fleetwood Mac, Buckingham has also released six solo albums and two live albums. As a member of Fleetwood Mac, he was inducted into the Rock and Roll Hall of Fame in 1998. In 2011, Buckingham was ranked 100th in Rolling Stone magazine's 2011 list of "The 100 Greatest Guitarists of All Time". In Fleetwood Mac's heyday, Buckingham was known for his finger picking guitar style and wide vocal range as well as the famous (sometimes tense) chemistry between himself and former girlfriend and fellow bandmate Stevie Nicks.

Born in Palo Alto, California, Buckingham was the third and youngest child of Rutheda (née Elliott) and Morris Buckingham. He had two older brothers, Jeff and Greg. Growing up in the San Francisco Bay Area community of Atherton, Buckingham and his brothers were encouraged to swim competitively. Though Buckingham dropped out of athletics to pursue music, his brother Greg went on to win a silver medal at the 1968 Olympics in Mexico City.

Terius Youngdell Nash (Born September 20, 1977), better known by his stage name The-Dream, is an American singer-songwriter and record producer. He is known for co-writing chart topping hits such as "Baby" for Justin Bieber, "Umbrella" for Rihanna and "Single Ladies (Put a Ring on It)" for Beyoncé, as well as for his three solo albums, Love Hate, Love vs. Money, and Love King.

Terius Nash was born in Rockingham, North Carolina and moved with his mother, Reva Nash, to Atlanta at the age of 3. He played trumpet, drums, and guitar as a child. His mother died in 1992 when Nash was fifteen years old, an event which would inspire him to write songs. He states that the death of his mother gave him a "soft spot" for women, which he credits to his desire to write songs about female empowerment such as Rihanna's "Umbrella". He moved in with his grandfather, a concrete mason who instilled a strong work ethic in young Nash. Of his grandfather, Nash recalls "He came out of a bad time for blacks in the South, but even though we lived in the hood, we had a boat, some cars and a house that was paid for. So I’ve always had a different outlook on life. There’s nothing I can’t do."
