The estate of the late rock musician Tom Petty have released extended, freshly mixed iterations of two signature tracks from Tom Petty and the Heartbreakers. The new versions of “American Girl” and “Breakdown” are now available across digital streaming platform, serving as a catalyst for an ongoing campaign that commemorates the 50th anniversary of the legendary rock group’s formation. The new mix of “American Girl” features a proper ending rather than the traditional fadeout that has been heard on radio for decades. While “American Girl” initially failed to achieve commercial chart success in the United States upon its release, the anthem has since transformed into an enduring cornerstone of popular rock culture.
