Bad Animals  by Heart

The 1987 album "Bad Animals" is the ninth album by Heart and marks the peak of their "mainstream" era, continuing their shift from the folk-rock of the '70s to the glossy arena rock sound. Hard Rock, Pop Rock, and Arena Rock with strong elements of '80s Glam Metal are the musical genres that Heart blend in Bad Animals. The album's name came from the band's ironic reaction when they were treated as "bad animals" in a luxury hotel in Memphis.

The sound is "glossy" and commercial, dominated by synthesizers and dynamic power ballads, while the guitars are more in the background compared to their past. The producer of the album was Rob Nevison, known for his ability to create radio hits. Thus, "Alone" became their biggest hit, staying at No.1 in the U.S. for three weeks.

The album reached No.2 on the Billboard and went triple platinum. In the United Kingdom, it reached No.7, where 300,000 copies were sold. Canadians brought the album to No.3 on their country's charts.
