It's hard to think of two more overworked pieces in the repertoire than Carl Orff's "Carmina Burana" and Maurice Ravel's "Bolero." The latter was overexposed by Bo Derek in 10; the former by just about every devil movie that ripped off its powerfully dark chorus. So why bother with Sofia Symphony and Chorus and Ballet Arabesk's touring performance of both? Well, for the "bonuses"; this is more musical spectacle than sedate symphony program. Orff's orchestration of medieval poems features a large chorus, hedonistic dancers, dramatic lighting and fantasy sets. For "Bolero," the French impressionist's erotic, snaking melody is accompanied by a ballet troupe. A great starting point for the classical novice, as well. Sat., Jan. 14, 8 p.m., Ruth Eckerd Hall, 1111 McMullen-Booth Road, Clearwater, $35, $40, 727-791-7400.
