''Windows of Heaven'' is Jefferson Starship's first studio album since reforming in 1992. It was first released in Germany, but the band told fans to wait for a new American remixed version. The single "Let Me Fly" was released along with the American release, but did not chart on the Billboard charts. Grace Slick joined the band in the studio to record vocals on "I'm on Fire" which only appears on the American and Japanese versions. The track "Maybe For You" appeared on the 2008 album, ''Jefferson's Tree of Liberty''. - Wikipedia
