Lazarus is the debut album by Gym Class Heroes lead singer Travie McCoy, released on June 8, 2010. McCoy announced his plans to pursue a solo career in early 2010, although he insisted that Gym Class Heroes had not broken up. After creating demos of melancholy and low-tempo songs, McCoy decided to abandon his early material and start over, as he claimed the songs were "too personal". He began to write more uptempo "party anthems" with lyrical themes of overcoming grief. Musically, McCoy draws from various influences on the record, including hip-hop, reggae, and rock. The album contains collaborations from Bruno Mars, Cee Lo Green, and T-Pain, among others.
Upon its release, Lazarus debuted at number twenty-five on the U.S. Billboard 200 chart with sales of 15,000 copies. The lead single from the album was "Billionaire", which peaked at number four on the Billboard Hot 100. The songs "Need You" and "We'll Be Alright" have also been released as singles. Critical response to the album has been mixed to positive, with most critics praising the album's upbeat songs yet criticizing the overabundance of featured collaborations. Gregory Heaney of Allmusic opined that "Even though every track on the album isn’t a keeper, it has some solid additions to any summer playlist and will definitely please fans of Gym Class Heroes."
