The 4th Annual Jiggle Jam Family Music Fest giggles, wiggles and jiggles into Downtown Kansas City on Memorial Day weekend, Saturday, May 26 and Sunday, May 27, 2012. Jiggle Jam brings generations and communities together to experience live music and educational activities in a fun and positive atmosphere that the entire family can enjoy. This isn't your typical kid's fest. It's a family music festival that's a rockin' good time for everyone!
