Bolton originally performed in the hard rock and heavy metal genres from the mid-1970s to the mid-1980s, both on his early solo albums and those he recorded as the frontman of the band Blackjack. He became better known for his series of pop-rock ballads, recorded after a stylistic change in the late 1980s.
Bolton's achievements include selling more than 75 million records, recording eight top 10 albums and two number-one singles on the Billboard charts, as well as winning six American Music Awards and two Grammy Awards. Bolton has received the Lewis Hine Award from the National Child Labor Committee, the Martin Luther King Award from the Congress of Racial Equality, and the Ellis Island Medal of Honor from the National Ethnic Coalition of Organisations.
The Hollywood Chamber of Commerce also recognised Bolton with a star on the Hollywood Walk of Fame for his musical and charitable contributions.
