 It can also be heard as an influence on artists as diverse as Billy Joel, Kid Rock and the Killers.Heartland rock faded away as a recognized genre by the early 1990s, as rock music in general, and blue-collar and white working class themes in particular, lost influence with younger audiences, and as heartland's artists turned to more personal works.Many heartland rock artists continue to record today with critical and commercial success, most notably Bruce Springsteen, Tom Petty, and John Mellencamp, although their works have become more personal and experimental and no longer fit easily into a single genre.
