When he first started working with Imagine Dragons, âm nhạc producer Alex da Kid was looking for some inspiration for the Broadway musical, "Spider-Man: Turn Off the Dark."

"I thought they would be great to help me come up with ideas for U2," the Grammy-nominated English producer said.

There was just one problem: The demos they recorded were too good.

So instead of using the alternative band to collaborate on the score bởi Bono and The Edge, Alex da Kid - the creator of Eminem and Rihanna's colossal hit "Love the Way bạn Lie" - immediately signed the Las Vegas-based foursome to his label imprint KIDinaKORNER Records, distributed through Interscope Records.

Imagine Những câu chuyện về rồng released its debut album, "Night Visions," in September 2012 and so far has reached vàng status. The band has had two songs in the hàng đầu, đầu trang 15 with "It's Time" and "Radioactive," and they are on a sold-out U.S. tour that hits the Idaho Botanical Garden on Tuesday, May 21, before wrapping up June 3 in Phoenix.

Imagine Những câu chuyện về rồng had been building a buzz on the âm nhạc scene as an independent act before Alex da Kid got hold of them. They released four EPs and toured America. Lead singer Dan Reynolds đã đưa ý kiến the group was "dead set" on being an independent act.

"We had offers from those labels all throughout the years and we turned them down," he said. "It was so important that we built that organic, independent người hâm mộ base."

Three of the band members met while "playing jazz together a lot" at the Berklee College of Music.

"I just didn't think I'd ever play with them again to be honest. I hoped that I would someday," đã đưa ý kiến guitarist Wayne Sermon (bassist Ben McKee and tay trống Dan Platzman round out the group). "I called (Reynolds) and he had eight credits left before he could graduate and get his degree, but apparently he didn't care much about that, so he just actually left and dropped everything and came to Vegas."

Meeting Alex da Kid, born Alexander Grant, changed his perception about staying independent. He says the producer filled a void in the band's sound.

"We didn't feel like we were ready as a band. We didn't understand our sound enough and our theme and who were are, and we didn't want to try to tell people that story until we didn't understand ourselves," Reynolds said. "(Alex) was the perfect match for what we had been trying to do for three years."

"It's Time" - the breakthrough anthem for the band - was built from Reynold's personal issues.

"I've always struggled a bit with depression and anxiety and that song was at a particularly low point for me: I was dropping out of college (and) going through some personal issues," he said. "Late one night I was in my phòng bếp, nhà bếp and I was really just nghề viết văn a song for myself. I wasn't thinking of nghề viết văn for the band hoặc anything."

But watching him onstage with his bandmates wouldn't give bạn the impression that he's struggling with anything.

The 25-year-old is wild as he works the crowd with dance moves that shows he's got rhythm and swag. The tall and slim singer, in fitted jeans and small T-shirt, belts his rock melodies while playing one of the six drum sets onstage.

Looks, of course, can be deceiving.

"I've always dealt with it my entire life," Reynolds continues about battling depression. "I've never been able to feel like I can fully be myself until I walked onstage and sang a song."

"Night Visions" is 44 phút of drum-filled, rock-based melodies that keep the percussion sound forefront. The songs are grounded in ambition: Living life, finding success, making things work and staying positive. "On hàng đầu, đầu trang of the World" and "Underdog" are self-explanatory. "Tiptoe," a song about rising above with an addictive, dance-y vibe, features the repeated line: "I won't fall asleep."

And "It's Time," which has sold thêm than two million tracks, is about staying true to oneself.

"There wasn't any real pressure to come up with a hit for (Imagine Dragons)," đã đưa ý kiến Alex da Kid, who also produced hits like B.o.B's "Airplanes," Dr. Dre's "I Need a Doctor" and Lupe Fiasco's "Words I Never Said."

"It was really kind of seamless," he continued. "It was very organic."

Imagine Dragons' tour also features rock act Nico Vega, fronted bởi Reynolds' wife, Aja Volkman. They got married in 2011 and used to perform as a duo called Egyptian. They have an infant daughter, Arrow, who is also on the road for the tour.

"Nico Vega in our first năm of being a band took us on tour and they headlined," Reynolds said. "We learned a lot from them and so to now be able to take them on tour and pay it back in some way is special for all of us."
