The band re-entered the studio during early 2010 and spent much of the year recording the group's third studio album. During this time, touring bassist Dallon Weekes joined the band's official lineup along with Urie and Smith, making the band a three-piece. Although Weekes did not perform on the upcoming album, he was responsible for the conceptualization of the cover art of the album and was also featured on the album cover, masked and standing in the background behind Smith and Urie. On January 18, 2011, the band revealed that an album titled "Vices & Virtues" would officially be released on March 22, 2011. The album was produced by Butch Walker and John Feldmann. The record's first single, "The Ballad of Mona Lisa", was released digitally on February 1, 2011, with the music video being released February 8, 2011. "Vices & Virtues" was officially released March 22, 2011, to relatively positive critical reviews.
