The band recorded its second albumFly or Die during 2003. The band actually learned the instruments needed to play the tunes, so they could perform live. As Chad Hugo told MTV News on December 8, 2003, "We're the ones playing the instruments live this time. I just started playing guitar last year so I'm learning as we go. Pharrell's playing drums. Last time, we didn't have time to learn certain instruments so we got Spymob to help us out." The band also recruited some assistance to record the album with Lenny Kravitz and Questlove playing on the track "Maybe." Several of tracks concern issues of particular concern to adolescents including "Thrasher" about bullies, "Drill Sergeant" about rebellion and conscription, and first love on "Backseat Love".
