"Best Of" albums usually spring up after a band's broken up or, as in this case, when they leave on label for another. It's another way for the record company to get a little more return on their investment. This will be a trip down memory lane for some who grew up on Petra's pop rock sounds. I don't think this album really appeals to headbangers too much, because even the rockers on this tape still don't get heavy and crunchy enough to classify as heavy metal. In concert, a lot of these tunes get beefed up for a more rockin' sound. "Shakin' the House", in my opinion, is their best tune. Glad to see it was included.
