Sherds from a jar of clay

For a few years in my life I listened to and bought some popular Christian Music, largely things like Amy Grant, Michael W. Smith, Stryper, Keith Green and largely because friends of mine were exposing me to it. Some of it was good and inspiring and had ok theology in the lyrics and some was probably less so though I doubt any of it was too bad. But I haven't really listened to much of it for over 10 years and have not kept up with the contemporary Christian music scene.
But in a recent issue World Magazine did an article on the group Jars of Clay and their new album, Redemption Songs, which "has reached into the past to produce a worship album that infuses the modern sound of bluegrass, blues, and soul with the poetic and theologically deep lyrics of 17th-, 18th-, and 19th-century hymns." I listened to some of the cuts on their website and like it and hope to order it soon (I didn't find it on my errands this weekend).
