One Degree of Separation
David Bruce Murray posits that, unlike CCM, an incredibly diverse genre, there is never more than one degree of separation between Southern Gospel artists. In other words, name any two artists (Inspirations and Martins) and you can find a group (Greater Vision) that could conceivably be paired with either in a joint concert.
Does this hold true?
Mike & Kelly Bowling and Blackwood Brothers?
Austin’s Bridge and the Melody Boys Quartet?
What do you think?
Blame it on whatever you like! Fact is, my reason is simple enough: I have no interest in any secular music.
