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.

Thomas Earl "Tom" Petty (born October 20, 1950) is an American singer-songwriter and multi-instrumentalist. He is the frontman of Tom Petty and the Heartbreakers and was a founding member of the late 1980s supergroup Traveling Wilburys and Mudcrutch. He has also performed under the pseudonyms of Charlie T. Wilbury, Jr. and Muddy Wilbury.

He has recorded a number of hit singles with the Heartbreakers and as a solo artist, many of which remain heavily played on adult contemporary and classic rock radio. His music, and notably his hits, have become popular among younger generations as he continues to host sold-out shows. Throughout his career, Petty and his collaborators have sold 60 million albums.

Tom Petty was born and raised in Gainesville, Florida, and attended Gainesville High School. His interest in rock and roll music began at age 10 when he met Elvis Presley. In the summer of 1961, his uncle was working on the set of Presley's film Follow That Dream in nearby Ocala, Florida and invited Petty to come down and watch the shoot. He instantly became an Elvis Presley fan and soon traded his Wham-O slingshot for a box of Elvis 45s. In a 2006 interview on the National Public Radio program Fresh Air, Petty said that he knew he wanted to be in a band the moment he saw The Beatles on The Ed Sullivan Show. One of his first guitar teachers was Don Felder, a fellow Gainesville resident, who would later join the Eagles. As a young man, Petty worked briefly on the grounds crew for the University of Florida, but never attended as a student. An Ogeechee lime tree that he planted while employed at the University is now called the Tom Petty tree.

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.
