Imagine Dragons will take to the stage with a performance of their brand new single “I Bet My Life,” the first music to be released from the Las Vegas quartet's upcoming second album. They are returning to the American Music Awards after winning “Favorite Artist - Alternative Rock” at 2013's event, where they also wowed the crowd with a performance of their hit, “Radioactive.” Formed in 2009 by vocalist Dan Reynolds, guitarist Wayne Sermon, bassist Ben McKee, and drummer Daniel Platzman, Imagine Dragons earned a grassroots following by independently releasing a series of EPs. After Alex Da Kid signed them to his KIDinaKORNER/Interscope label, the band made its major-label debut with the release of “Continued Silence,” a 2012 EP featuring the 2x platinum breakthrough single “It's Time.” The band's double-platinum album “Night Visions” arrived later that year and Imagine Dragons found themselves on a skyward trajectory that saw the album debut at No. 2 on the Billboard Top 200 Albums chart, sell nearly four million copies worldwide, and became the No. 1 album on Spotify Worldwide for 2013. “Night Visions’” second single, the 9x platinum “Radioactive,” hit No. 1 on the Billboard Rock chart and earned the band a 2014 Grammy for “Best Rock Performance.” It is the best-selling rock song in U.S. digital history. The third single, “Demons,” hit No. 1 at Alternative and Top 40 radio, and has sold 3.9 million copies in the U.S. The band has sold more than 24 million tracks worldwide.
