Bruce Frederick Joseph Springsteen (born September 23, 1949), nicknamed "The Boss," is an American singer-songwriter-performer who records and tours with the E Street Band. Springsteen is widely known for his brand of heartland rock, poetic lyrics, and Americana sentiments centered on his native New Jersey.

Springsteen's recordings have included both commercially accessible rock albums and more somber folk-oriented works. His most successful studio albums, Born in the U.S.A. and Born to Run, showcase a talent for finding grandeur in the struggles of daily American life; he has sold more than 65 million albums in the United States and more than 120 million worldwide and he has earned numerous awards for his work, including 21 Grammy Awards, two Golden Globes and an Academy Award. He is widely regarded by many as one of the most influential songwriters of the 20th century, and in 2004, Rolling Stone ranked him as the 23rd Greatest Artist of all time.

Springsteen was born in Long Branch, New Jersey, and spent his childhood and high school years in Freehold Borough. He lived on South Street in Freehold Borough and attended Freehold Borough High School. His father, Douglas Frederick Springsteen, was of Dutch and Irish ancestry and worked, among other vocations, as a bus driver, although he was frequently unemployed; his surname is Dutch for jump stone. His mother, Adele Ann (née Zerilli), was a legal secretary and was of Italian ancestry. His maternal grandfather was born in Vico Equense, a city near Naples. He has two younger sisters, Virginia and Pamela. Pamela had a brief film career, but left acting to pursue still photography full time; she took photos for the Human Touch and Lucky Town albums.

Thomas Baptiste Morello (born May 30, 1964) is a Grammy Award-winning American guitarist best known for his tenure with the bands Rage Against the Machine, Audioslave, his acoustic solo act The Nightwatchman, and his newest group, Street Sweeper Social Club. Tom is also the co-founder (along with Serj Tankian) of the non-profit political activist organization Axis of Justice, which airs a monthly program on Pacifica Radio station KPFK (90.7 FM) in Los Angeles. He is best known for his unique and creative guitar playing style, which incorporates feedback noises, unconventional picking and tapping as well as heavy use of guitar effects. He was ranked #26 in Rolling Stone's list of the "100 Greatest Guitarists of All Time."

Tom Morello was born on May 30, 1964, in Harlem, New York, to Ngethe Njoroge and Mary Morello. Tom is of Irish and Italian descent on his maternal side, and Kikuyu Kenyan descent on his paternal side. His mother was a schoolteacher from Marseilles, Illinois, who earned a Master of Arts at Loyola University, Chicago and travelled to Germany, Spain, Japan, and Kenya as an English language teacher between 1977 to 1983. His father was a Kenyan participant in the Mau Mau Uprising, and served as Kenya's first ambassador to the United Nations. Morello's paternal great-uncle, Jomo Kenyatta, was the first elected president in Kenyan history. His parents met in August 1963, while attending a pro-democracy protest in Nairobi, Kenya. After discovering her pregnancy, Mary returned to the United States with Njoroge in November, and married in New York City.

Neil Percival Young,OC,OM (born November 12, 1945) is a Canadian singer-songwriter who is widely regarded as one of the most influential musicians of his generation.

Young began performing as a solo artist in Canada in 1960, before moving to California in 1966, where he co-founded the band Buffalo Springfield along with Stephen Stills and Richie Furay, and later joined Crosby, Stills & Nash as a fourth member in 1969. He forged a successful and acclaimed solo career, releasing his first album in 1968; his career has since spanned over 40 years and 34 studio albums, with a continual and uncompromising exploration of musical styles. The Rock and Roll Hall of Fame website describes Young as "one of rock and roll’s greatest songwriters and performers". He has been inducted into the Hall of Fame twice: first as a solo artist in 1995, and second as a member of Buffalo Springfield in 1997.

Young's work is characterized by his distinctive guitar work, deeply personal lyrics and signature alto or high tenor singing voice. Although he accompanies himself on several different instruments, including piano and harmonica, his idiosyncratic electric and clawhammer acoustic guitar playing are the defining characteristics of a varyingly ragged and melodic sound. While Young has experimented with differing music styles, including swing and electronic music throughout a varied career, his best known work usually falls into two primary styles: acoustic (folk and country rock) and electric (amplified hard rock, very often in collaboration with the band Crazy Horse). Young has also adopted elements from newer styles such as alternative rock and grunge. His influence on the latter caused some to dub him the "Godfather of Grunge".
