Heartland rock is a genre of rock music that developed in the 1970s and reached its commercial peak in the 1980s, when it became one of the best-selling genres in the United States. It was characterized by a straightforward musical style, a concern with the average, blue collar American life, and a conviction that rock music has a social or communal purpose beyond just entertainment. The genre is exemplified by the commercial success of singer-songwriters Bruce Springsteen, Bob Seger, Tom Petty and John Mellencamp, along with less widely known acts such as Southside Johnny and the Asbury Jukes and the Iron City Houserockers. It was also associated with a number of country music artists including Steve Earle and Joe Ely. In the 1990s, many established acts faded and the genre began to fragment, but the major figures have continued to record with commercial success.

The term heartland rock was not coined to describe a clear genre until the 1980s. In terms of style it often uses straightforward rock and roll, sometimes with elements of Americana and country. Most artists avoided the synthezisers that dominated the electronic rock of the 1980s and placed an emphasis on guitars, with a basic rhythm and blues line-up of drums, keyboards and occasional horn section instruments like a saxophone. Lyrics are often presented in a style that is raspy and unpolished, adding a sense of "authenticity". It was most strongly influenced by American folk and folk rock acts such as Hank Williams, Woody Guthrie,Bob Dylan, The Byrds, Creedence Clearwater Revival, and the Northern Irish but heavily American-influenced Van Morrison, as well as the basic rock of 1960s garage and the Rolling Stones.

John Mellencamp,(born October 7, 1951) is an American rock singer-songwriter, musician, painter and occasional actor known for his catchy, populist brand of heartland rock which emphasizes traditional instrumentation. He has sold over 40 million albums worldwide and has amassed 22 Top 40 hits in the United States. In addition, he holds the record for the most tracks by a solo artist to hit number-one on the Hot Mainstream Rock Tracks chart, with seven, and has been nominated for 13 Grammy Awards, winning one. His latest album, No Better Than This, was released on August 17, 2010 to widespread critical acclaim.

Mellencamp is also one of the founding members of Farm Aid, an organization that began in 1985 with a concert in Champaign, Illinois to raise awareness about the loss of family farms and to raise funds to keep farm families on their land. The Farm Aid concerts have remained an annual event over the past 26 years, and as of 2012 the organization has raised over $39 million to promote a strong and resilient family farm system of agriculture.

Robert Nesta "Bob" Marley, OM (6 February 1945 – 11 May 1981) was a Jamaican singer-songwriter and musician. He was the rhythm guitarist and lead singer for the ska, rocksteady and reggae band Bob Marley & The Wailers (1963–1981). Marley remains the most widely known and revered performer of reggae music, and is credited with helping spread both Jamaican music and the Rastafari movement to a worldwide audience.

Marley's music was heavily influenced by the social issues of his homeland, and he is considered to have given voice to the specific political and cultural nexus of Jamaica. His best-known hits include "I Shot the Sheriff", "No Woman, No Cry", "Could You Be Loved", "Stir It Up", "Get Up Stand Up", "Jamming", "Redemption Song", "One Love" and, "Three Little Birds", as well as the posthumous releases "Buffalo Soldier" and "Iron Lion Zion". The compilation album Legend (1984), released three years after his death, is reggae's best-selling album, going ten times Platinum which is also known as one Diamond in the U.S., and selling 25 million copies worldwide.
