Two more plays opening tonight: Shadowlands the love story of C.S. Lewis and Joy Davidman at Germantown Community Theatre; and the comedy Hay Fever at Playhouse on the Square. Tonight s art openings are at Jubilee Gallery, for Frank Frazier, Africa in April s honorary artist; Cooper-Young Gallery, for an exhibit of paintings by Chuck Zimmer; and at the University of Memphis for The Waiting Room, an installation of paintings, photos, poems, videos, and sculpture by Richard Kamler, all done to recreate the environment of a death-row waiting room. On a much lighter note, good ol REO Speedwagon is at the Horseshoe Casino tonight, while Wynonna is at Sam s Town. Here at home, the wonderful, wandering mariachi band Los Cantadores is at Automatic Slim s. Ashville, North Carolina, country punk band Unholy Trio is at Hi-Tone. The Reba Russell Band is at Patrick s. Yamagata and those civilized hellions Accidental Mersh are at The New Daisy. And last but certainly not least, today s biggest, most historic event is the Stax Ground Shakin Ground Breakin ceremony at the original site of Stax Records at College and McLemore. This is, of course, the ground-breaking for the new Stax Museum of American Soul Music, Music Academy, and Performing Arts Center. This has been a long time coming, and one of the best things that s ever happened to this city. A large number of former Stax artists will be performing, and it s all free and open to the public. Starts at 9 a.m.
