"Heavy Metal Rules" was released in September 2019. The disc, which is described in a press release as a "heavy metal version of a self-help manual and ultimate party album combined," was once again produced byJay Ruston, who collaborated with the band on all of its previous recordings, including 2017's "Lower The Bar".
STEEL PANTHER specializes in imitating and exaggerating the less flattering aspects of 1980s hair metal, with unrepentantly crude, non-PC sexual content as a favorite lyrical theme.
