It's 1 a.m. and Mardi Gras World is still kicking. Spring breakers and locals alike are packed tight to see some of today's top acts in EDM, hip-hop and indie rock. With shows starting at dusk and ending at three in the morning, the two-day festival known as Buku only got more crowded and more rowdy as the night progressed.

Peabody Opera House welcomed the addictive sounds of Passion Pit to the stage on Tuesday night.
