Mark Hall and company stripped down some of their biggest hits to get to the guts of each track and better showcase the heart behind the lyrics. The result is an acoustic project that relies on guitar, mandolin and violin to do the heavy lifting, and in the process gives the songs more weight as well. As a teaser, there are two new tracks here -- "Delivered" and "Only You Can Satisfy" -- and they hold up well against the other eight Casting Crowns faves. This simpler sound, which has an almost bluegrass feel to it, suits this band of worship leaders well. Maybe they should unplug more often.
