Students working in the Science Center’s Perlik Commons on Wednesday afternoon were treated to a surprise performance by Rust Belt Rapper, a student dance group on campus. The group performs Rapper Sword Dance, a traditional folk dance that originated in northern England. The group’s routines feature five members that each perform with flexible, double-handled swords and spin, duck and occasionally flip through the quintet’s different formations. In addition to several unannounced performances in spaces across campus this week, held in the hopes of recruiting new members for next year’s team, the group performs at the Student Dance Showcase and Dandelion Romp and has previously competed at tournaments.
