Crazy concert concept pits Ludacris, Neon Trees in head-to-head competition

It was a concert experience unlike any other concert experience. Atlanta's own Ludacris squared off against the Neon Trees in a head-to-head competition Monday night.

The Georgia World Congress Center played host to the Red Bull Soundclash. Rain from Tropical Storm Lee forced the event, originally scheduled for outside, inside the GWCC. Nearly 2000 fans showed for the event.

The Red Bull Soundclash featured two stages on the opposite sides of the facility. In the middle, sat a raised DJ booth. On one stage, rapper Ludacris belted out his hits. Across the floor, hard rock band the Neon Trees delivered their songs. But this wasn't an event where one band played their set and the other followed. At the Soundclash, the musicians played off each other.

The competition featured five rounds. The warm-up round consisted of each band playing three of their own songs. That was followed by the cover. In it, both performed their own versions of Michael Jackson's "PYT." The Takeover was the third round. It was a collaborative round where one band started playing one of their own tunes then the other group took over mid-song to finish it out with their own flair. Round four was the clash. This round challenged the bands versatility as they adapted their songs to the music genres of DJ Mick Boogie’s choice – reggae, acoustic, and metal. The fifth and final round was the wild card round. In it, the bands pulled out all the stops and surprises to win the crowd over.

When it was all said and done, at least one person left the arena pumped about the event. Ludacris tweeted, “Red Bull Soundclash is one of the best concerts of my life!!!”
