The Used, whose last album, 2007"s Lies For the Liars, debuted at No. 5 on the Billboard Top 200, spent the first half of 2008 in LA exploring and refining tangential riffs and melodies into a scattering of songs that contained a surprisingly cohesive sensibility. The band members dubbed the music they were writing "gross pop," their own new genre of hook-laden numbers that pushed the boundaries of what defines the extreme simplicity and indescribable complexity of rock music.
