Music ruined Mike Krol's life. And then saved it. In 2015, Mike Krol found himself in the midst of an existential crisis.

He'd invested everything to create the rock-and-roll life he'd always wanted, but he wasn't sure the life wanted him back.

Power Chords, Krol's new Merge release, picks up where Turkey left off. It traces Krol's journey back to punk rock, harnessing both the guitar technique and the musical redemption referenced in its title.

To rediscover the power in those chords, Krol recorded for two-plus years in three separate locations (Nashville, Los Angeles, and Krol's native Wisconsin).

The record opens in a howling maelstrom of feedback: welcome to Krol's crucible. After a stage-setting spoken-word intro, we find ourselves back in familiar Krol territory_aggressive and assertive, scratchy and raw, catchy as hell_but something has changed.

The sounds have a new density_and so do the stories. Krol's lyrics have always walked a fine line between self-acceptance and selfdestruction, but throughout Power Chords, they reveal a new sense of self-awareness.

Of course, none of this is to say that Krol has mellowed. You might find a mea culpa or two, but Mike Krol will never be chastened.

If anything, he's out more for revenge than forgiveness, and if he's grown, it's because he's grown bolder.

He's wielding the same influences_Misfits, The Strokes, early Weezer, Ramones_but turning up the gravity and the gain.

Indeed, Krol has gone somewhere new; yes, he bludgeoned himself with over-analysis and self-loathing, but along the way he stumbled upon a trove of intricate guitar lines and artfully mutating melodies.

It's there in the chorus of "Blue and Pink," the bridge in "I Wonder," the entirety of the deliriously infectious first single, "An Ambulance."
