Sisters Ann and Nancy Wilson are the creative spark behind Heart, a hard rock group who initially found success in the mid-'70s, only to reach greater heights after engineering a major comeback a decade later. The daughters of a Marine Corps captain, Ann (born June 19, 1950) and Nancy (born March 16, 1954) grew up in both Southern California and Taiwan before the Wilson family settled in Seattle, WA. Throughout their formative years, both were interested in folk and pop music; while Ann never took any formal music lessons as a child (she later learned to play several instruments), Nancy took up guitar and flute. After both sisters spent some time at college, they decided to try their hand as professional musicians, and while Nancy began performing as a folksinger, Ann joined the all-male vocal group Heart.
