Joan Jett and the Blackhearts are a rock band that emerged in the early 1980s, fronted by guitarist and vocalist Joan Jett. Known for their raw, stripped-down sound that combined elements of punk and hard rock, they are best recognized for their hit single "I Love Rock 'n Roll", which topped the Billboard Hot 100 chart in the US. The band's influence extends beyond their music, with Jett becoming a cultural icon for her defiant, rebellious image. Their significance in music history lies in their contribution to the rise of female-fronted rock bands and their impact on the punk genre.
