Diwali, presented by Ashoka, celebrated its 30th anniversary this weekend with dancing, theatrics and music. This year’s performance marks decades of bringing a spectacle of sound, color and, most importantly, light to the Edison Theatre.

The sounds of India mixed with modern American pop to fill the 560 Music Building on Saturday in a concert featuring Penn Masala, a South Asian a cappella group from the University of Pennsylvania. The concert was orchestrated by Washington University’s chapter of GlobeMed, a network of college students that partners with global health organizations to improve the health of those around the world living in poverty.
