Chastian Park is the perfect outdoors venue for the Jackson's Unity Tour. Personally, some of my best concert experiences EVER were in Chastain Park. However, I'm not so sure I would buy a ticket to see these guys. At the very least, I would need for them to come with a Pepper's Ghost (often called a hologram) of Michael Jackson. They don't sound too bad though...
