On December 4, 2017, a parallel project titled Back to the Rock II was released, bringing re-recordings from other 1980s' hits and giving continuity to the previous "Back to the Rock". This time, the line-up does not take the name of Classic Petra, but the name of CPR Band instead. The members of this formation are: Greg X. Volz, on lead vocals; Kirk Henderson, on guitar; John Lawry, on keyboards; Ronny Cates, on bass (who would be replaced later by Greg Bailey) and Louie Weaver, on drums.
