Sounds like … the familiar punk rock of Relient K, MxPx, Green Day, and Sum 41 with some power pop and bubbly '80s rock thrown in reminiscent of Weezer, All Star United, and The CarsAt a glance … Hawk Nelson's sophomore effort is impressively varied and catchy, stretching beyond the conventions of the punk rock genre, but it ultimately fails to communicate much in the way of spiritual substanceTrack Listing The One Thing I Have Left The Show Bring 'Em Out Everything You Ever Wanted Something on My Mind Is Forever Enough Zero Nothing Left to Show Head on Collision Hello It's Over 14

When Hawk Nelson debuted in the summer of 2004, they seemed just another follower of Relient K and MxPx in a market already crowded with punk-pop bands. Less than two years later, it's hard to ignore their impact. Selling more than 100,000 copies of their debut Letters to the President, the Canadian band made an appearance in 2005's remake of Yours, Mine & Ours and performed "My Generation" as The Who on NBC's American Dreams. Fans voted them as Best New Artist in CCM magazine and crowning them Best Band with Ignite Your Faith.

Fans are obviously clamoring for more, and many of the same ingredients are here for Smile, It's the End of the World. Aaron Sprinkle (Kutless) is back in the producer's chair and Trevor McNevan (Thousand Foot Krutch) again co-wrote the songs, but only half the band from the first album has returned. Joining lead singer Jason Dunn and bassist Daniel Biro are guitarist Jonathan Steingard and drummer Aaron Tosti, who have both toured as part of Hawk Nelson in the last year. They're apparently part of the band's musical growth, as Hawk Nelson sounds even better than before.

They remain rooted in catchy punk rock, as heard in "Bring 'Em Out" and "The One Thing I Have Left." But like Relient K, they're not content with offering the same predictable style ten or twelve times over an album. Hawk Nelson knows how to change it up with healthy doses of power pop, adding spice to songs like "Nothing Left to Show" and "It's Over" while successfully rendering ballads like "Zero" and "Everything You Ever Wanted."

Better still are the songs that owe as much to Weezer and The Cars as The Ramones and Green Day, particularly the ultra-catchy '80s rock of "The Show." The harmony heavy "Head On Collision" is as much fun as All Star United ever was, and the same is true of the bouncy shuffle and kazoos in "Hello." While the buoyant "Something on My Mind" crosses punk with the piano pop of Ben Folds or Ian Eskelin, a far heavier rock sound characterizes "Is Forever Enough."

p>Smile is one fun album, and knows it too. Tracks like "The Show," "Something on My Mind," and "Bring 'Em Out" are party songs that seem to exist purely for amusement-almost inane, but does anyone really care when they're this catchy? The romantic little nothing "Hello" indicates how times have changed when Dunn sings, "You're so fine, been on my mind/Get nervous every time I see you hop online." And no album like this would be incomplete without a breakup song like "It's Over," though from the way this brokenhearted lament is phrased, you can't help but wonder what might have been if it were tweaked to double as a spiritual metaphor longing to restore a relationship with God.
