World Grotto will send a local performer to the Trinumeral Music and Arts Festival in Asheville, N.C., in September. The Market Square club is hosting a performance contest on Thursday, Aug. 13, for Knoxville-area bands and musicians to compete for a one-hour slot at the festival, which runs Sept. 9-13. Each performer at the contest will have 30 minutes on stage. Audience members will be asked which performer they’ve come to see; the band or musician with the most audience picks wins. To enter, contact Brad Keats at brad(at)trinumeral(dot)com.
