Hailing from the era of big hair and even bigger guitar riffs, Petra Praise - The Rock Cries Out is a sleek, metallic platter of fist-pumping, full-throated praise and worship. The material is composed, primarily, of traditional Christian songs of devotion—including “King of Kings” and “I Will Call Upon the Lord”—but the skyscraping rock style is pure Petra. This isn’t the album you put on for nuance or reflection; it’s the one you play for aggression, conviction, and in-your-face devotion—or just to play air guitar.
