Here are some great images from one of summer's most exclusive performances.

Right here in Tennessee.

It's the 'Synchronous Firefly Show' in the Smoky Mountains.

Driven by pure animal passion, they come alive when the lights go down.

Generating ooohs and ahs on a stage that only nature could build.

Fireflies are the hot ticket. These are even showier than your backyard variety., the tens of thousands of lightning bugs flash in harmony

This year 21,000 people vied for 1800 coveted passes for an evening with the bright lights of Mother Nature.

If you hope to go next year, you'll want to plan ahead.
