Indecent Obsession (also seen as Obsession) were an Australian pop rock band formed early in 1987 in Brisbane with founding mainstays Daryl Sims on drums and Michael Szumowski on keyboards. By 1988 the line-up also included Andrew Coyne on lead guitar and David Dixon on lead vocals. They released three studio albums, Spoken Words (November 1989) and Indio (August 1992), both reached the top 50 on the ARIA Albums Chart. In 1990 Spoken Words was repackaged for United States market as Indecent Obsession, which reached the Billboard 200. In May 1989 they issued their debut single, "Say Goodbye", which peaked at No. 6 on the ARIA Singles Chart – their highest position in Australia. Their second single, "Tell Me Something" (September), reached No. 17 nationally. When issued in the US it peaked at No. 31 on the Billboard Hot 100. It reached No. 1 in Indonesia and Hong Kong, and Top 10 in Japan and South Africa. For the Asian market the band used the shortened name, Obsession. In 1992 they were the first Western act to tour South Africa after the lifting of the cultural isolation during the apartheid era. They were "greeted by screaming fans and scenes of mass hysteria", both their second album, Indio, and one of its singles, "Kiss Me", peaked at No. 1 on the relevant South African charts. By 1993 Sims and Szumowski were joined by Mark Gray on bass guitar, Richard Hennassey on lead vocals and Graham Kearns on lead guitar. The following year they issued another studio album, Relativity, before disbanding a year later.
