Looking like something from another planet, the phenomenal Blue Man Group makes a landing at Blumenthal's Belk Theater. Using music, comedy and stage props, the performance art trio has made its mark. They don't speak, but as the ol' saying goes: "Actions speak louder than words." In this case, the technological theatrics say it all. Drumming, fans and psychedelic images make the show as groovy as it is engaging. $20 and up. April 19-21, 7:30 p.m.; April 22, 8 p.m.; April 23, 12 p.m., 4 p.m. & 8 p.m.; April 24, 3 p.m. Belk Theater, 130 N. Tryon St. 704-372-1000. www.blumenthalcenter.org.
