SteelHeart’s self titled debut album ‘SteelHeart’ was released in 1990, bringing them almost immediate commercial success, with critics comparing their forceful hard rock sound to Led Zeppelin’s. Since then, Miljenko and band-mates have showcased their broad influences and the raw strength of his vocals; their sound drawing comparisons to hard rock and pop metal greats like Ratt and Whitesnake. The original line up included Miljenko Matijevic (Vox, Guitar, Piano), Chris Risola (Guitar), Frank Di Costanzo (Guitar), James Ward (Bass), and John Fowler (Drums). The guys found themselves hitting the big time as their first album reached #40 on the Billboard 200 chart in 1990, the band’s fan-base growing swiftly around the world. “SteelHeart” sold 33,000 albums on its first day in Japan alone. Before long, the album hit platinum – and its power ballad, “She’s Gone,” hit #1 on the international charts, staying there 17 weeks. The second single, “I’ll Never Let You Go (Angel Eyes)” reached #14 on the Billboard charts. Another song, “Can’t Stop Me Loving’ You” further showcased Miljenko’s vocal range, but this time, Risola’s lead guitar skills were also noticed. SteelHeart’s next effort album-wise, “Tangled In Reins,” released July 10, 1992, had a more mixed eclectic song style. With heavy hitting, hard driving songs like “Loaded Mutha”, “SteelHeart”, “Electric Love Child”, and fun loving “Sticky Side Up,” to tear jerking ballads such as “Mama Don’t You Cry.” to name a few. The song, “SteelHeart” featured Miljenko hitting the highest note of his song catalogue. While the ballad “Mama Don’t You Cry” charted #1 in many East Asian Countries, including Hong Kong, prompting their live unplugged performance in Hong Kong followed by an extensive unplugged tour of Asia in September, 1992. The album did not reap the same commercial success as StealHeart’s debut album, reaching only #144 on Billboard charts, signaling the grunge-sound invasion was starting to take force in the music business.
