Heart is an American rock band formed in 1967 in Seattle, Washington, as The Army. Two years later they changed their name to Hocus Pocus. The year following they changed their name to White Heart, and eventually changed the name a final time to Heart, in 1973. By the mid-1970s, original members Roger Fisher (guitar) and Steve Fossen (bass guitar) had been joined by sisters Ann Wilson (lead vocals and flute) and Nancy Wilson (rhythm guitar, vocals), Michael Derosier (drums), and Howard Leese (guitar, keyboards and backing vocals) to form the lineup for the band's initial mid- to late-1970s success period. These core members were included in the band's 2013 induction into the Rock and Roll Hall of Fame.
