Of all the breakups in Mike Krol’s songs, the most harrowing story is about his breakup with music. In 2015, coming off of his best record yet and the ensuing world tour, Krol found himself in the midst of a full-blown 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 2015’s 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.
