"Phil and Casper are some of the best guitarists in the world," Mueller says.
In 1988, Keaggy won his first Dove Award for his instrumental album, "The Wind and the Wheat." In 1992 he won again for "Beyond Nature," and has been voted a top finger-style guitarist three years in a row by Guitar Player Magazine.
Meanwhile, McCloud, pastor of Upper Room Fellowship which meets at the church, is an accomplished musician who produced two albums with Atlantic Records and portrayed John Lennon on Broadway.
You can read more about McCloud, his friendship with Keaggy, what led him to the Holly Springs area and his spiritual path in "Music With a Message," which appeared on Canton Patch in 2011.
The concert is Friday, April 12, at 7 p.m. at Church of Messiah, 415 Charles Cox Drive. The concert is free, but a $10 offering is suggested.
