famous members, convincing Hartman, who still was not touring but had never stopped writing and playing guitar in the studio, to join Schlitt and Weaver as the label-marketed version of Petra. Studio musicians, including bassist Rick Cua, filled in the rest. The result was a well-received album, helped in part by an Inpop gimmick that comprised sending radio executives and media representatives an unlabeled CD of the album and asking them to guess – many doing so futilely – what band had recorded it.
