3 Doors Down is an American rock band from Escatawpa, Mississippi that formed in 1996. The band originally consisted of Brad Arnold (vocals/drums), Todd Harrell (bass guitar) and Matt Roberts (guitar).They were soon joined by guitarist Chris Henderson, and later by drummer Richard Liles, who played for the band during their tour supporting their first album. Daniel Adair played drums on tour from 2002–2005. This configuration played nearly 1,000 shows across the world following the release of their hugely successful Away from the Sun album. In 2005, when Adair was hired full-time by Nickelback, Greg Upchurch (Puddle of Mudd) joined to play drums full-time. In 2012, original guitarist Matt Roberts departed due to health issues. Chet Roberts, who was formerly Chris Henderson's guitar tech, took his spot. In 2013, Harrell was ejected from the band after being charged with vehicular homicide. Bassist Justin Biltonen replaced him.

The band rose to international fame with their first single, "Kryptonite", which charted in the top three on the Billboard Hot 100 chart. The band then signed onto Republic Records and released their debut album, The Better Life, in 2000. The album was the 11th-best-selling album of the year and was certified 6x platinum in the United States. Their second album, Away from the Sun, (2002) continued the band's success; it debuted at No. 8 on the Billboard 200 chart, went multi-platinum in the United States like its predecessor, and spawned the hits "When I'm Gone" and "Here Without You". The band followed it up by extensive touring for two years before releasing their third album, Seventeen Days, in 2005. The album debuted at No. 1 on the Billboard 200 chart and was certified platinum within its first month of release. Their fourth, self-titled album, 3 Doors Down (2008), also debuted at No. 1 on the Billboard 200 chart. The band's fifth studio album, Time of My Life (2011) debuted at No. 3 at the charts.
