Panic at the Disco's sophomore album, "Pretty. Odd.," has only been out since March 25, but the Las Vegas-based quartet has already begun writing new material for its third offering. "I wouldn't say we have an album's worth [of material] but we definitely started writing on the road, which is something we had never done before," singer/guitarist Brendon Urie said during an interview with LiveDaily. "We had a little anxiety toward writing anywhere other than [places] we felt comfortable--like home. We realized we could be anywhere as long as we're with each other."While Panic at the Disco's debut, "A Fever You Can't Sweat Out," was a flamboyant affair, "Pretty. Odd." carries a more classic, retro, mellow vibe. Urie explained that the third album is shaping up as a logical progression. "It's still more classic because we're still listening to a lot of older stuff," Urie explained. "It's in the same vein as this record. I'm not saying the next record is going to sound like this one. It's too early to say. It's a little different sounding, I guess."As was the case with "Pretty. Odd.," the members of Panic at the Disco--who also include guitarist Ryan Ross, bassist Jon Walker and drummer Spencer Smith--are sharing writing duties on the next album. "The first time around, we were still kind of getting used to each other and getting to know each other a little bit," Urie said. "[On 'A Fever You Can't Sweat Out,'], Ryan wrote all the lyrics, and then we would work on the music together. This time around [on "Pretty. Odd."], we realized it made sense for us to branch out and use everybody's talents."On the road headlining the Honda Civic Tour, Panic at the Disco will appear on the debut of "FN MTV Premieres," hosted by Pete Wentz of good friends Fall Out Boy, June 13 at 8 pm ET/PT. The band's tour ends June 14 in Anaheim, CA, however, Urie said he expects his band to perform again in the US this fall.
