LOUISVILLE, Ky. (WDRB) -- It's Louisville's signature event of the summer -- but before Forecastle music rumbles the Ohio River, we're hearing sounds of setup and seeing what makes this year's festival bigger than ever.

The stage is set -- literally -- for a party in the park along the Ohio River.

"It's a huge, massive structure," said Derrick Pedolzky, the crew manager. "And we're going to have some awesome music on it."

"We transform Waterfront Park into a magical little kingdom that only exists for one weekend of the year," said Holly Weyler, Forecastle spokeswoman.

This is Forecastle weekend. Sixty acts will be featured on four different stages. Headliners range from groups like OutKast to Beck.

"There's always moments where the right artist plays the right chord at the right time and I happen to catch it and you get goosebumps," said Pedolzky.

Derrick Pedolzky started as a volunteer seven years ago when Forecastle was still a bunch of friends playing in the park. He's watched the event grow to the 65,000 who are expected this year -- and he's now managing the entire crew.

"I don't think people realize that when you buy a ticket to a festival like this, you're coming for an amazing experience -- but there are hundreds of people that the experience, for them, is putting it together," he said.

Hands work at a fevered pace, trying to create the perfect atmosphere.

"Three days to load the stage and the deck in and then we have another day for lighting and sound," Pedolzky said. "This is the biggest stage that Forecastle has ever had. It's like the end zone to a football field. OutKast is bringing a giant video wall so every seat is like a front-row seat."

"Seventy percent of our visitors come in from out-of-town and fill our hotels and restaurants in Louisville," said Weyler. "Last year we did 14 million in economic impact on the city."

"We're now on the level of being a national player as far as music festivals, right here in Louisville Kentucky," she added.

Pedolsky still hoping that each guest leaves with goosebumps.

"To have this big of a festival in Louisville, Kentucky and still have some local people involved -- it's amazing," he said. "I feel pretty honored to be a part of it."
