Heart is an American rock band formed in 1970 in Seattle, Washington, by Steve Fossen (bass guitar), Roger Fisher (guitar), David Belzer (keyboards), and Jeff Johnson (drums). It evolved from an existing band, White Heart. The vocalists for Heart are sisters Ann Wilson (lead vocals, flute, guitar) (born June 19, 1950) and Nancy Wilson (vocals, guitar, mandolin) (born March 16, 1954). Heart rose to fame in the mid-to-late-1970s with music influenced by hard rock and heavy metal, as well as folk music. The band's popularity declined in the early 1980s, but it began a successful comeback in 1985 which continued into the mid-1990s.
