Unseen Power is the thirteenth studio album by Petra, originally released in 1991.
The album retains a driving edge while veering away from the more commercial pop-metal sound of their previous efforts. Bob Hartman has stated that he and the producers intentionally chose to move in directions they were not instinctively inclined to go.
Track listing includes:
• Destiny
• Who’s on the Lord’s Side
• Ready, Willing & Able
• Hand on My Heart
• I Need to Hear from You
• Dance
• Secret Weapon
• Sight Unseen
• Hey World
