There's nothing we love more here at the Arkansas Times than local concerts with diverse and full line-ups of local music. Put it all towards a good cause and that's icing. On Saturday, the Sierra Club presents “Energy Shift,” a night of music and activism focused on their campaign to stop dirty coal-fired plants from being built in Arkansas. In the lobby, show-goers will have the opportunity to sign petitions, film video postcards for the governor and more. But here's probably the real draw: Eight acts will perform, including two Times Showcase finalists, rap/R&B duo Epiphany with Gina Gee and post-punks Kyoto Boom, and two Showcase semi-finalists, rapper Rockst*r and the pop-rock outfit the Reds. Plus: R&B crooner Sean West, blue-eyed soul and synth man Browningham (who's performing a new set), pop-rockers Big Boots and Goines, a Pine Bluff MC who seems to channel every slight and ill inflicted on him into sharp and seductive raps.
