There have been at least three bands with this name.

1) In 1962, before David Crosby had tasted any fame, he and his girlfriend gave up their newborn baby boy for adoption. In 1995, Crosby was reunited with that son, James Raymond, only to discover that Raymond had developed some serious musical and songwriting talents of his own, without ever knowing who his real father was. They began writing songs together almost immediately, with the first product being "Morrison," a jazzy rock tune reflecting Crosby's anger over Jim Morrison's portrayal in the Oliver Stone film, "The Doors."

Soon they enlisted Jeff Pevar, a well-traveled session guitarist who had played with Crosby & Nash, and formed the band CPR, using an acronym from their surnames. Their vocal harmonies recall Crosby, Stills & Nash at their best, but the music has a jazzy flavor and a healthy disrespect for pop convention that's much more reminiscent of bands like Steely Dan. Including their eponymous debut album in 1998, CPR has released two studio albums and two live albums, and continue to tour occasionally.

2) A largely instrumental hard rock band featuring bassist Randy Coven (Steve Vai, Yngwie J. Malmsteen), guitarist Al Pitrelli (Trans-Siberian Orchestra, Megadeth, Savatage) and drummer John O. Reilly (Blue Öyster Cult, Rainbow), named for an acronym of their surnames and released a one-off self-titled album in 1992. Zakk Wylde (Ozzy Osbourne, Pride & Glory), Randy Jackson (Zebra), Vito Bratta (White Lion) and Steve Morse (Deep Purple) contributed guest appearances.

3) CPR (Classic Petra Resurrection) is a band comprised of former members of Petra. It features Greg X. Volz on vocals, Louie Weaver on drums, John Lawry on keyboards, Greg Bailey on bass, and Kirk Henderson on guitar. They have released on album ("Back To The Rock II") containing re-recorded versions of Petra songs as well as a cover of "Dream On" by Aerosmith.

C.P.R is also an acronym used by Colorado Public Radio for their podcasts. Read more on Last.fm. User-contributed text is available under the Creative Commons By-SA License; additional terms may apply.
