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's hard rock style, while Criss's album featured an R&B style with multiple ballads. Simmons's was the most diverse of the four, featuring hard rock, ballads, Beatles-influenced pop and a cover version 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.
