Every other Tuesday at 11 a.m., rock out on the Impala Lawn at the zoo.
This week, grab your kids, some lunch and your dancing shoes and enjoy the sounds of Yosi and the Superdads.
Can't make it on August 17? No worries, check out Secret Agent 23 Skidoo on August 31.
The concert is free with the price of zoo admission.
Another cool event at the Philly Zoo is Roar and Snore Under the Stars. And it's just what it sounds like -- a slumber party, outside, for the whole family.
Hang at the zoo after hours for $50 a person.
Call 215-243-5254 to reserve a spot for your tent.
