Think “Movin’ Out’’ meets “In the Heights’’ and you’ll get some idea of ‘‘Intergalactic Transfer Students.’’ The show (also described as a hip-hopera) is about saving the world from the violence and negativity of mainstream rap. Our rapper heroes, Virtue and Papa Bakes, encounter aliens, conquer danger, and explore new worlds. Dancers act out the other characters. Pictured: Dave Dorvilier (left), Hilary Sayers, and Sean Bjerke as “Whack Emcees.’’ 8:30 p.m. through Feb. 6. $15, $20 at the door; $10, $15 at the door for students; $5 discount for Feb. 3 preview. Recommended for ages 14 and older. Calderwood Pavilion, 527 Tremont St., Boston. 617-933-8600. www.bostontheatrescene.com
