“Annie” now playing at the Riverside Center for the Arts has regained its position as a first-class musical. “Why,” you may ask? Because it has a first-rate, A++ cast! Not only that, the seven-piece orchestra conducted by Carson Eubank supports this production perfectly and can stand on its own (and does in several joyous instances). Additionally, the heroic set by Frank Foster includes brilliant projections curated by director Patrick A’Hearn that indelibly stamp the era in your mind before the show even opens and appear occasionally during the show to great advantage.
