The album became the band's breakthrough hit, reaching #2 in the UK charts and #17 in the US, making it the most successful Free album. The album contained the hit single "All Right Now" which they later played to a crowd of over 600,000 people at the 1970 Isle of Wight Festival, generating great popularity. To date, it is the only Free album to have seen a CD reissue in America.
Document 2: I Feel Free: "I Feel Free" is a song first recorded by the British rock band Cream. The song's lyrics were written by Pete Brown, its music by Jack Bruce. It was the first track on the U.S. issue of their debut album, "Fresh Cream" (1966), and the band's second hit single (the first being "Wrapping Paper"). As with all tracks on Cream's U.S. debut, producer's credit went to Robert Stigwood.

Featuring integral contributions from each of the group's four members, the album was recorded in October 1968 at Olympic Studios in London and established their fusion style of both blues and rock music. It also attracted a large and devoted following to the band; Zeppelin's take on the emerging hard rock sound endeared them to parts of the counterculture on both sides of the Atlantic Ocean.

The band has gone through many lineup changes throughout its career. The only member to appear in every lineup is drummer Simon Kirke. He is the only member of the band to have performed at every Bad Company concert and to appear on every album. Mick Ralphs is currently still a part of the band but is being temporarily replaced by former Black Crowes guitarist Rich Robinson for the bands 2016 United States tour. While still officially a member of the band in 1990-1991, Ralphs also sat out most of their Holy Water tour. This time he was temporarily replaced by Geoff Whitehorn.
Document 6: Blue &amp; Lonesome (The Rolling Stones album): Blue & Lonesome is a covers album by the Rolling Stones—their 23rd British and 25th American studio album—released on 2 December 2016. It is the band's first album to feature only cover songs, and their first studio release since 2005's "A Bigger Bang". Despite the short time length just around 43 minutes, this album released as a double LP to maintain the clarity like CD. "Just Your Fool", a Buddy Johnson cover (though the Rolling Stones version is based on Little Walter's arrangement) was released as the first single from the album on 6 October. Eric Clapton contributed guitar on two tracks.
Document 7: Faces (band): Faces were an English rock band formed in 1969 by members of Small Faces after lead singer/guitarist Steve Marriott left that group to form Humble Pie.

Document 8: The Moody Blues: The Moody Blues are an English rock band formed in Birmingham in 1964. They first came to prominence playing rhythm and blues music, but their second album, "Days of Future Passed", which was released in 1967, was a fusion of rock with classical music and established them as pioneers in the development of art rock and progressive rock. It has been described as a "landmark" and "one of the first successful concept albums". They became known internationally with singles including "Go Now", "Nights in White Satin", "Tuesday Afternoon" and "Question". They have been awarded 18 platinum and gold discs. The Moody Blues have sold 70 million records worldwide.
Document 9: Free discography: The discography of Free, an English blues rock band, consists of six studio albums, two live albums, 18 compilation albums, one extended play, 16 singles and two video albums.

The album entered the US "Billboard" 200 chart at number 197. Free's self-titled second album failed to chart, before the 1970 follow-up "Fire and Water" peaked at number 2 on the UK Albums Chart, supported by the popular single "All Right Now" which reached the same position on the UK Singles Chart. The single also reached the top ten in a number of other regions, including the United States where it peaked at number 4 on the "Billboard" Hot 100.
Document 10: Free (Free album): Free is the second album by English rock group Free, recorded and released in 1969. The band had spent time touring after their debut album "Tons of Sobs" the previous year, and there is a marked difference in the musicianship of the band as well as Paul Rodgers's voice. Whereas "Tons of Sobs" had been produced by Guy Stevens, "Free" was produced by the head of Island Records, Chris Blackwell.
Document 11: Tons of Sobs: Tons of Sobs is the debut album by English blues rock band Free, released in the UK on 14 March 1969. While the album failed to chart in the UK, it did reach #197 in the US. Free are cited as one of the definitive bands of the British blues boom of the late 1960s even though this is the only album of their canon that can strictly be called blues rock. The title of the album does not relate directly to the content of the album; it is possibly oblique reference to the darker, more sombre moments of the record.
Document 12: Black Sabbath (album): Black Sabbath is the debut album by the English rock band Black Sabbath. Released on 13 February 1970 in the United Kingdom and on 1 June 1970 in the United States, the album reached number eight on the UK Albums Charts and number 23 on the "Billboard" charts. Although it was poorly received by most contemporary music critics at the time, "Black Sabbath" is now widely considered the first heavy metal album.
Document 13: Free (band): Free were an English rock band formed in London in 1968, best known for their 1970 signature song "All Right Now". They disbanded in 1973 and lead singer Paul Rodgers went on to become a frontman of the band Bad Company along with Simon Kirke on drums. Lead guitarist Paul Kossoff formed Back Street Crawler in 1975, but died from a pulmonary embolism at the age of 25 in 1976. Bassist Andy Fraser formed Sharks.
Document 14: The Animals discography: The discography of The Animals, an English music group of the 1960s formed in Newcastle upon Tyne, contains 20 studio albums, 6 compilation albums, 5 EPs and 25 singles. Featuring a gritty, bluesy sound and a deep-voiced frontman in Eric Burdon, they are best known for their rendition of an American folk song named "House of the Rising Sun", which is described by many as their signature song. This single had worldwide sales of nearly 5 million and became a Number One hit in both the UK and US in 1964. Overall, the group balanced tough, rock-edged pop singles such as "We Gotta Get Out of This Place" and "It's My Life" against rhythm and blues-oriented album material. The Animals released separate UK and US albums, a practice common to other British Invasion bands of the time such as The Beatles and The Rolling Stones.
Document 15: Bad Company: Bad Company is an English hard rock supergroup formed in Westminster, London, in 1973 by two former Free band members—singer Paul Rodgers and drummer Simon Kirke—as well as Mott the Hoople guitarist Mick Ralphs and King Crimson bassist Boz Burrell. Peter Grant, who managed the rock band Led Zeppelin, also managed Bad Company until 1982.
