With less than 30 days until Lights All Night, the Dallas-based electronic music festival is switching venues.

The two-day event is moving to Dallas Market Hall on Stemmons Freeway, per an announcement Thursday. Lights All Night was originally scheduled to take place at the Kay Bailey Hutchison Convention Center, the fest's home of three years (2011, 2013 and 2014). The lineup includes DJs Kaskade, Hardwell, Porter Robinson and Big Gigantic, among others.

A Q&A that came with the press release attributed the move to the rare availability of Dallas Market Hall.

"We just recently found out that the space was available and were able to strike a deal," said Scott Osburn, co-founder of Highland Productions, which throws Lights All Night.

According to the convention center, however, that may not have been the only reason.

"Lights All Night will not be held at the Kay Bailey Hutchison Convention Center Dallas this year because they do not have a contract with us," said Danielle McClelland, spokeswoman for the facility. Highland Productions never did for the 2015 event, she said.

So what happened between the festival's original summer announcement and Thursday? We're not clear. McClelland couldn't offer details, and neither Osburn nor his partner Hank Keller could be reached for comment by phone, email or social media.

Though producers gushed that the new, 202,000-square-foot venue offers an opportunity to create the largest main stage in the fest's history and a second stage that will "make the fan feel as though they've entered another world," many ticket holders are less thrilled about the news. Keller said in the release that 25 percent of Lights All Night attendees travel in from out of town, which means they've likely already made lodging arrangements.

Now in its sixth year, Lights All Night annually draws about 40,000 attendees, mostly Millennials dressed in costume. Festival alumni include Skrillex, Armin van Buuren, Icona Pop, Deadmau5 and Major Lazer. See the crazy pictures from years past below.
