Calhoun’s Gem Theatre has announced two upcoming performances at the restored downtown theatre.

The a capella group Committed, NBC television’s “The Sing-Off” season 2 champions, will appear at the Gem on Saturday, Feb. 25 at 8 p.m., sponsored by Downtown Calhoun, and the Chamber Players of the South will present their “American Classics” concert, featuring Rhapsody In Blue and Appalachian Spring, on Saturday March 3 at 7:30 p.m., sponsored by the Harris Arts Center and Gem Theatre.

Committed, the six-man a capella group, creates unique harmonies with powerful lead vocals and a booming bass line. They arrange all of their own music using only their vocals as instruments to emulate a full band sound.

Committed’s debut album is an eclectic mix of jazz, gospel, blues and R&B wrapped into one sound. The album features a mix of original tunes and hand-selected cover songs.

The Chamber Players of the South is a 25 member professional chamber orchestra.

Its members also perform with orchestras in Rome, Macon, Savannah, Chattanooga, and Birmingham.

The piano soloist for the Rhapsody is Dr. Rebekah Jordan-Miller. She has performed widely, both as a soloist and as a collaborative artist in venues throughout Canada, the United States, Austria, Australia, and Norway.

Tickets for the Committed performance are $15 each. Tickets for the Chamber Players of the South concert are $20 general admission; $18 for Harris Arts Center and GEM members, $10 for students 18 and under
