VocalEssence Ensemble Singers, together with Don Shelby (former WCCO news anchor) as Mark Twain, celebrate life on the Mississippi River. Through choral music and the spoken word, VocalEssence takes listeners on a musical journey of the past and present-choral masterpieces, favorite folksongs, traditional spirituals, and Americana-all paired with the words of Mark Twain in River Songs & Tales on Wednesday, April 4 at 7:30 p.m. at Wilcox Theater, REIF Center.
