For Panic At The Disco's sophomore follow-up to their Decaydance/Fueled By Ramen break-through debut, 2005's "A Fever You Can't Sweat Out," the band holed up in a Las Vegas studio with renowned producer Rob Mathes. What they created is nothing short of a masterpiece, the '60s pop-inspired "Pretty. Odd." This time around, the band opted for real instruments and live tracking over Pro Tools software, citing influences as The Beach Boys, Bob Dylan, and The Beatles.
