in 2013. The band's experiences on the tour served as an inspiration for their second album. In 2012, Imagine Dragons released their debut
studio album Night Visions. The album, produced by the band along with
Alexander Grant and
Brandon Darner, launched the band into international mainstream commercial success, charting within the top ten of 14 national
record charts, in addition to charting on eight others. Certified Platinum by seven national music associations, including 2× Platinum in the United States by the
RIAA and 3× Platinum in Canada by
Music Canada, the album was initially met with first week sales in excess of 83,000 copies, the highest charting for a debut rock album since 2006. The album was also nominated for the 2014
Juno Award for International Album of the Year. The band released six
singles during the
Night Visions album cycle in 2012 and 2013, five of which charted on the
Billboard Hot 100. "
Radioactive," a 2013 single, sold more than nine million singles in the United States, spending more than one year consecutively on the Billboard Hot 100. Peaking at no. 3 on the chart, it also broke the record for the longest run into the top five and is the best-selling rock single on the Nielsen SoundScan running list of best-selling rock tracks in digital history.
Billboard listed the band as one of "2012's Brightest New Stars" and later "The Breakout Band of 2013." To further promote the already-successful
Night Visions, the band set out on a year-long concert tour beginning in early 2013 and ending in mid-2014, dubbed the "
Night Visions Tour." The tour spanned for over 170 dates, and visited North America, South America, Europe and Oceania. An additional tour of North America, dubbed the "Into the Night Tour," was also executed. The conclusion of the Into the Night Tour signaled the end of the
Night Visions album cycle, with
Night Visions Live, a
live album, serving as the last release in the cycle. Lead singer
Dan Reynolds joked about the end of the
Night Visions cycle, saying that "We're always writing on the road, [so] that second album will come,
unless we die at the age of 27 next year. Hopefully we don't die and there will be a second album. I don't know when it will be, but it may come." The band were also inspired greatly by their experiences on the Night Visions Tour. Dan Reynolds told
New Orleans–based
newspaper The Times-Picayune that the world tour had "a lot of inspiration to be drawn," and further stating, "You kind of realize that you're a lot smaller than you think." The idea behind the second studio album, dubbed as their "
new year's resolution," was to create music and finish it when the band feels that their work is done. Reynolds told
MTV in 2014 that the band wanted to "put out an album that [they're] really happy with". He further said that "we tend to be perfectionists, too hard on ourselves at times, and we don't want to rush anything because we know how we are with things. We don't want to put a record out until we really feel good about it, you know, and who knows how long that will take." ==Composition==
