Passage: Kiss were at their commercial peak by 1978. Alive II was the band's fourth platinum album in just under two years, and the ensuing tour had the highest average attendance (13,550) in the group's history. In addition, Kiss' gross income for 1977 was $10.2 million. The group, along with manager Aucoin, sought to take the band to the next level of popularity. To that end, an ambitious, two-pronged strategy was devised for 1978.The first part involved the simultaneous release of four solo albums from the members of Kiss. Although Kiss has claimed that the solo albums were intended to ease rising tensions within the band, their 1976 record contract did in fact call for four solo records, with each of them counting as half an album toward the group's five-record commitment. Each album was a solo effort (none of the group appeared on another's album), and were all released and marketed as Kiss albums (with similar cover art and poster inserts). It was the first time that all current members of a rock band had released solo albums on the same day.For the band members, it was a chance to showcase their individual musical styles and tastes outside of Kiss, and in some cases to collaborate with contemporary artists. Stanley's and Frehley's albums were most similar to Kiss' hard rock style, while Criss' album featured an R&B style with multiple ballads. Simmons' was the most eclectic of the four, featuring hard rock, ballads, Beatles-influenced pop and a cover of "When You Wish upon a Star" from the Disney film Pinocchio. Simmons' many collaborators included Aerosmith's Joe Perry, Cheap Trick's Rick Nielsen, the Doobie Brothers' Jeff "Skunk" Baxter, Donna Summer, Janis Ian, Helen Reddy, Bob Seger, Katey Sagal and his then-girlfriend Cher.
