Even those who don't know anything about classical music are bound to have heard the Hallelujah chorus of George Frederic Handel's MESSIAH, which could be the audio equivalent of a fireworks display. As part of the ASO's Holiday Pops series, Norman Mackenzie conducts the Atlanta Symphony Orchestra and Chamber Chorus in a sure-to-be stirring rendition of Handel Thurs., Dec. 13, and Sat., DEC. 15, as well as Bach's Christmas Oratorio. Featured singers include mezzo-soprano Kelley O'Connor, soprano Cyndia Sieden, tenor Richard Clement and bass Gerard Sundberg. $19-$57. 8 p.m. Atlanta Symphony Hall, 1280 Peachtree St. 404-733-5000. www.atlantasymphony.org.
