A busy day. Tonight, the Playwright s Forum s production of Little Red Wagon Painted Blue opens at TheatreWorks. There s an opening reception at Memphis Botanic Garden for an exhibit of works by Lisa Rivas. Today kicks off the Second Annual One Festival: A Road Trip to the Heart of God, a rather different kind of spiritual gathering at Shelby Farms, with 90 live bands and lots of other entertainment. Tonight s Seagram s Gin Live concert at the Mid-South Coliseum features Mystikal, Jagged Edge, Jaheim, and Ludacris. And last but certainly not least, today begins the 4th Annual Indie Memphis Film Festival of Southern Films at The Orpheum, the Historic Daisy, and other downtown venues. If you don t see anything else, catch Smokestack Lightning, a documentary about barbecue from the folks who wrote the book of the same name (showing Friday). It features, among others, Mr. J.C. Hardaway of the Big S Lounge, arguably the greatest chef on Earth and one of the most lovable people you ll ever have the good fortune to meet.
