Heart is an American rock band formed in Seattle, Washington, in 1967. The band developed from earlier projects led by Roger Fisher (guitar) and Steve Fossen (bass guitar), including The Army (1967–1969), Hocus Pocus (1969–1970), and White Heart (1970–1973). By 1975, the lineup consisted of Fisher, Fossen, Ann Wilson (lead vocals and flute), Nancy Wilson (rhythm guitar, vocals), Michael Derosier (drums), and Howard Leese (guitar, keyboards, backing vocals). This lineup was part of the band's early period of commercial success and was included in Heart's 2013 induction into the Rock and Roll Hall of Fame.
Heart's music incorporates elements of hard rock, heavy metal, and folk music. Between the late 1970s and early 1980s, the band underwent lineup changes, with Fisher, Fossen, and Derosier leaving by 1982. They were replaced by Mark Andes (bass) and Denny Carmassi (drums). Although the band's commercial success declined during the early years of this new lineup, Heart experienced a resurgence in the mid-1980s, with popular radio singles continuing into the 1990s. Heart disbanded in 1998 but has reunited multiple times for touring and recording, with the Wilson sisters remaining the consistent members.
The band's US Top 40 singles include "Magic Man" (1975), "Crazy on You" (1976), "Barracuda" (1977), "What About Love" (1985), "Never" (1985), and "All I Wanna Do Is Make Love to You" (1990), along with number one hits "These Dreams" (1986) and "Alone" (1987). Heart has received four Grammy Award nominations and has sold over 50 million records worldwide, including approximately 22.5 million albums in the United States. The band has achieved top-ten albums on the Billboard 200 across the 1970s, 1980s, 1990s, and 2010s.
