Local gem Hillsburn gets a well-deserved headlining spot at this year's Pop Explosion (the band describes itself as "every bit as anthemic as Florence + The Machine, but with soaring three-part harmonies thrown in for good measure") while Devarrow—the Halifax-based troubadour who melds Save Your Scissors-era City and Colour lyricism with Bon Iver-on-espresso vibes—makes arriving early a must.
