Blink-182 is an American pop punk band consisting of vocalist and bass guitarist Mark Hoppus, vocalist and guitarist Tom DeLonge, and drummer Travis Barker. The band achieved greater success with 1999's multi-platinum selling Enema of the State, which reached number 9 on the Billboard 200 on the strength of the singles "What's My Age Again" and "All the Small Things", the latter of which became the highest-charting song of their career by reaching number 6 on the Billboard Hot 100. Blink-182 gained popularity for their irreverent sense of humor, and the follow-up album Take Off Your Pants and Jacket (2001) reached number 1 in the United States, Canada, and Germany. The eponymously-titled Blink 182 followed in 2003 and was a stylistic shift for the group, infusing experimental elements into their usual pop punk formula which resulted in a more mature sound. At the 51st Grammy Awards ceremony on February 8, 2009, DeLonge, Hoppus, and Barker appeared onstage together for the first time since December 2004. Barker announced the band's reformation, stating that "we used to play music together, and we decided we're going to play music together again", with Hoppus adding "Blink-182 is back!" Blink-182 is currently headlining the 10th Annual Honda Civic Tour with My Chemical Romance, which runs from August to October 2011.
