Earlier this week, he shot the video for his latest single, "Explode.""A lot of things are happening," Freedia said, adding that Hurricane Katrina and the subsequent levee failures in 2005 brought attention to the city's music scene and the bounce genre. "I had put in my time working in club after club after club for years, and when Katrina hit, it was time for me to see the world," he said. Buku opens Friday with Primus 3D, Zedd, Aeroplane, Flying Lotus, DJ Soul Sister, Kid Cudi and more than a dozen other acts. Joshua Steele, the British DJ who goes by the stage name Flux Pavilion, said he'll be playing jams from his new album, "Blow the Roof," when he takes the stage Friday. "I play what makes me happy, what gets me up and jumping around," he said. Flux Pavilion, whose hits include 2011's "Bass Cannon," delivers high-energy shows that "mix it up a lot, to keep it interesting," Steele said. "As an artist, you can do whatever you want with bass music, and that's the beauty of it," he said. "It's whatever the producer wants it to be. It can be samba, hip-hop, heavy metal, anything really. You can go anywhere with it." The Internet has increased accessibility to electronic music, diminishing the genre's "underground" image, Steele said. "It's a free platform, an open database, where you can just go find it for yourself," he said. Dante DiPasquale of Winter Circle Productions, the New Orleans-based company producing Buku, said although the festival is bigger than last year, it is intentionally being kept small in comparison to other music festivals. There are only 10,000 tickets available for each day, he said. Mardi Gras World adds to the "only in New Orleans" experience, he said. "This festival is really paying tribute to New Orleans, to what people in New Orleans and in the South are listening to," he said. "The rooted music, the jazz music, it's important, but the up-and-coming DJs, bounce artists and indie bands are driving the music today."
