On Saturday night, members of the MIT Ballroom Dance Team gathered in Kresge Auditorium to perform their second annual dance concert. Elaborately costumed dancers took the stage, sometimes in pairs and sometimes in groups, to perform nearly 20 different numbers in styles including tango, waltz, cha-cha, and samba (the viral Korean hit “Oppa Gangnam Style” even made an appearance). The MIT Ballroom Dance Team consists of MIT undergraduates, graduate students, and other MIT-affiliates. Members have been working on planning the concert since April. The concert also featured guest performances by the MIT Asian Dance Team and by MIT’s South Asian Fusion dance team, Chamak.
