Wednesday afternoon, we got a chance to sit in on a full dress rehearsal of The Gospel at Colonus. The music alone, featuring the Blind Boys of Alabama, the Steeles, and Charleston's own Royal Missionary Baptist Church, is enough to get you to the Gaillard. But if you aren't up-to-date on your knowledge of Oedipus, you may want to take a little CliffsNotes refresher course. Spoleto is currently offering a buy-one-get-one-free deal on tickets. Our official review is right here.
