Heart is an American rock band that first found success in Canada and later in the United States and worldwide. Over the group's four-decade history it has had three primary lineups, with the constant center of the group since 1974 being sisters
Ann Wilson (lead singer) and
Nancy Wilson (guitarist). Heart rose to fame in the mid-1970s with music influenced by
hard rock and
heavy metal as well as
folk music. Their popularity declined in the early 1980s, but the band enjoyed a comeback starting in 1985 and experienced even greater success with
album oriented rock (AOR) hits and hard rock ballads into the 1990s. With
Jupiter's Darling (2004),
Red Velvet Car (2010), and
Fanatic (2012), Heart made a return to its hard rock and acoustic folk roots.
