Adam Mitchel Lambert (born January 29, 1982) is an American singer-songwriter and stage actor. Born in Indianapolis but raised in San Diego, Lambert had dreamed of becoming a performer after appearing in numerous amateur productions in his childhood and adolescence. His passion overtook him when deciding to drop out of college, pursue his career, and perform in various professional theatrical productions across the world. Lambert came to prominence following his appearance on the eighth season of American Idol. Although he was runner-up, Lambert launched a music career with the release of his debut studio album For Your Entertainment (2009) after signing with 19 in a joint venture with RCA. Debuting at number three on the Billboard 200, selling 198,000 copies in the U.S. in its first week, and reaching the top 10 in several countries worldwide, the album subsequently achieved international success with its singles "For Your Entertainment", "Whataya Want from Me" and "If I Had You". Soon after, he embarked on his first headlining worldwide concert tour, Glam Nation, making him the only American Idol contestant to do so in the year following his Idol season. The tour was followed by two live releases: an extended play entitled Acoustic Live! (2010), and a live CD/DVD Glam Nation Live (2011), which debuted at number one on the SoundScan Music Video chart. Lambert took executive producer credit and was a principal writer on his second studio album, Trespassing, which was released to critical acclaim on May 15, 2012. Trespassing made its debut in the number one spot on the Billboard 200 album chart, also topping the Billboard Digital Albums Chart and Canada's Digital Albums Chart. With this accomplishment, Lambert makes music history as the first openly gay artist to achieve the top charting position. Citing influence from various artists, Lambert has become recognized for his flamboyant, theatrical and androgynous performance style, and his powerful and technically skilled tenor voice with multi-octave range. He has accrued numerous awards and nominations, including a Grammy nomination for Best Male Pop Vocal Performance, and has sold nearly two million copies of his debut album worldwide as of April 2012 and 4.2 million singles worldwide as of January 2011. The Times identified Lambert as the first openly gay mainstream pop artist to launch a career on a major label in the U.S., while The LA Times ranked him fifth in its list of the top 120 American Idol contestants.
