American Midwest Ballet presents “Momentum” on Oct. 14 and 15. The production is a showcase of the range of ballet, and will include Erin Alarcón’s “Fragile Creatures,” which hauntingly explores the mysterious world of memory; Monique Haley’s “Love Games,” depicting the flirty tug-of-war we play when falling for someone; Joffrey Ballet co-founder Gerald Arpino’s “Confetti,” a sparkling classical jewel; and Erika Overturff’s “Go West!,” is an exuberant celebration of the spirit and stories of the American West.
