A young member of The Salvation Choir begged forgiveness for the ensemble’s Christian faith and for not singing in English prior to a performance at Theis Park on Sunday, July 17. Her unnecessary apologies were the only thing I didn’t admire about the energetic presentation. Only about 50 were on hand when the large group began its set at the Nelson-Atkins Museum of Art’s free Lawn Party. Forty-five minutes later, more than 300 people were caught up in the jubilant celebration. Presumably consisting of several sets of children and their parents, the refugees specialize in an evangelical variation of the Congolese rumba popularized by Franco. And just like that, the Salvation Choir is my favorite locally based band.
