The continued silence from the American alternative rock band, Imagine Dragons, has finally ended after three years as their second studio album, “Smoke + Mirrors,” debuted on Feb. 17.

Four guys and Las Vegas: That marked the beginning of a musical exodus for the band initially established by Dan Reynolds in 2009. The present members of the group include frontman Reynolds, guitarist Wayne Sermon, bassist Ben McKee, and drummer Daniel Platzman.

High expectations were sure to be met due to the band’s breakout in 2012 with “Radioactive,” which was labeled the biggest rock hit of the year.

“Smoke + Mirrors,” alluded to the representation of illusions versus reality with inspiration from the own individual lives of the members, opened with “Shots,” which was released as the third single from the album.

It was one of the album’s most prominent songs as a casual yet touching work about apologizing and regret. But the smooth beat set the bar a little too high for the rest of the album and cast the “happy illusion” shadow over the rest of the album’s bipolar tones.

The band explored many different moods and meanings among its songs, such as “Dream,” which fell into a melancholy trance-like rhythm until the melodious chorus appeared only to fall back into the steady drum beat. Similarly, “Summer” also included notes of sentimental beats that suggests reminiscence.

The first official single, “I Bet My Life,” was a familiar rendition that possessed many of the band’s distinct styles. The line, “I’ve told a million lies but now I tell a single truth,” underlies a subtle story of forgiveness and mistakes.

“Trouble” seemed like a spin off of an Avicii song with “I want no trouble” making up 95% of the words.

“Friction” starts off like a rusty banjo playing at a campfire until a variety of yelling, whispering, gospel singing, and techno voices are added that make one feel that they’re in a Mazda car commercial or about to rob a bank with the screamo-like voice encouraging you, “You can’t fight the friction.”

Mediocre points were found throughout the album in pieces such as “Gold,” where there were more random keyboard button features used than actual voices.

But “I’m So Sorry” wrought hope for the album with its heavy guitar rock beat, that may cause spastic dance movements, accompanied by again emphasizing the need for apology and forgiveness.

“The Fall” ended the album with a musical whisper that eventually led into the expected introduction of the drums but later fell into lapses of peaceful yoga-like instrumentals.

“Smoke + Mirrors” undoubtedly has some notable, but mediocre, moments in the album but when compared to its predecessor, “Night Changes,” there is no doubt that it does not live up to the quality and drive behind the 2012 debut.

The legacy of “Radioactive,” “It’s Time,” and “Demons” from the Imagine Dragons previous album will be hard to surpass.

Despite the somewhat substantial growth of the band seen through his album, it is also notable that the themes have gained more depth and meaning.

This album is overshadowed by the glorification of the first success, trying to feed people off a watered version of the same hype. I do not imagine dragons as much as I imagine more of sleeping puppies with nightmares.

I give this album 2 out of 4 grizzly paws.
