Imagine Dragons is an American alternative rock, indie rock, and pop rock band. They are based in Las Vegas, Nevada. The current members of the band are: Dan Reynolds as lead vocalist/frontman, Ben McKee on keyboard and bass, Wayne Sermon on lead guitar, and Daniel Platzman on drums.

Imagine Dragons formed in 2008 when Dan Reynolds and Andrew Tolman met each other studying at Brigham Young University. They brought in three other members to join the band: Andrew Beck (guitar), Dave Lemke (bass), and Aurora Florence (piano). The five-piece band released the song “Speak to Me” that same year. However, two members of the band – Beck and Florence – also left in 2008.

Andrew Tolman recruited his longtime friend Wayne Sermon in 2009 as a replacement. Sermon played guitar and had graduated from Berklee College of Music. Tolman also asked his wife, Brittany, to play the keyboard and perform backup vocals. When Lemke left the band, Sermon recruited a fellow Berklee College of Music student, Ben McKee. He played bass and completed the lineup.

Imagine Dragons initially played in their hometown city of Provo, Utah. They gained a large following there until they moved to Las Vegas. In 2011, they went to the studio to record “It’s Time”. They finished the recording before they signed a record deal.

Pat Monahan, the frontman for Train, fell sick before the Bite of Las Vegas Festival in 2009. When Train was pulled out from the lineup, Imagine Dragons were called in as replacement. They performed before a crowd of 26,000 people. Since then, the band has won many awards in Las Vegas such as being named as the Best CD of 2011 by Vegas SEVEN and the Best Local Indie Band 2010 by Las Vegas Weekly.

In 2011, the band signed a record deal with Interscope Records. They worked with Alex da Kid (a Grammy winning record producer) for their new record. During this time, the Tolmans left the group and Daniel Platzman and Theresa Flaminio were brought in as replacements. In 2012, Flaminio departed the band, which left the band with its current four-piece lineup.

The band’s single “It’s Time” reached #15 on the Billboard Hot 100 chart. They also released its music video on April 2012 on MTV. That same year, the song was nominated for the “Best Rock Video” category at the MTV Video Music Awards. The single also reached double platinum status.

Meanwhile, the band’s debut album Night Visions was finished recording in the summer of 2012. They released it in September 2012 and it reached #2 on the Billboard Hot 200 chart. Their debut album sold over 83,000 copies upon its first week of being released. The song “Radioactive” was a hit when it sold over 7 million singles in the U.S. alone. It also spent 87 weeks on the Billboard Hot 100 charts. Since then, the band has released two more albums: Smoke + Mirrors and Evolve.
