If Paint The Night is the 60th headliner, and World of Color Celebrate! is the 60th's sleeper hit, then I think Disneyland Forever will be the big bruiser heavyweight that puts a giant exclamation point on each evening of the Diamond Celebration summer. If I wasn't in mixed company on a family website, I might also say that Disneyland Forever is the, um... twin circular objects of the 60th entertainment offerings.
I've seen this fireworks show testing for many nights the last few weeks from my hillside home in Villa Park. And I've been watching Disneyland fireworks from there for 20 years. Disneyland Forever is quite clearly the biggest and baddest show they've ever done. With the in-park projection effects and rooftop elements, this one will be impressive and jaw-dropping and memorable.
Video and pictures online won't do this show justice, as it never does when it comes to fireworks. But this looks like it's going to be a very big and chest thumping kind of a show!
