When five guys can kick it a capella style, they don't need instruments. Tonight, a group of musicians will bring its show A Rockapella Holiday, featuring lots of holiday songs, to McGlohon Theatre. The super cool thing about this group is that they actually used to be a house band on the PBS TV show Where in the World is Carmen Sandiego? Crazy, huh? $34 and up. Dec. 15, 7:30 p.m.; Dec. 16, 7:30 p.m. McGlohon Theatre, 345 N. College St. 704-372-1000. www.blumenthalcenter.org.
