While Foreigner took a brief hiatus, Gramm made his solo debut in 1987 with Ready or Not and scored a major hit with "Midnight Blue." Foreigner reconvened and recorded another platinum-selling album, Inside Information, but Gramm maintained his solo success with 1989's Long Hard Look and soon left group to form his own band, Shadow King, which released its self-titled debut on Virgin Records in 1991. Shadow King proved to be short-lived, however, and in 1994 Gramm and Jones revived Foreigner for the release of Mr. Moonlight.
As the decade drew to an end, Gramm was sidelined with several health issues. He was diagnosed with a benign brain tumor on the eve of the band's planned Japanese tour in 1997, and the surgery that followed damaged his pituitary gland. After a year of rehabilitation and radiation treatment, the singer made a full recovery and resumed touring in 1999. He split with Foreigner once again in 2003, however, preferring to tour in support of his solo material instead. ~ Jason Ankeny, Rovi
