Sam Hunt’s mushy, electro-lite “Body Like a Back Road” has rewritten the rules for what hit country singles sound like, and Jon Pardi is about as far from Sam Hunt’s style of country as possible. The 32-year-old singer from near Sacramento broke through last year with California Sunrise, an album full of ringing guitars and working-man’s anthems like “Paycheck”; Pardi would have easily been labeled a throwback if he didn’t strike such a chord with today’s fans. Sunrise bowed at No. 1 on Billboard’s country albums chart, produced two Top 5 singles in “Dirt On My Boots” and “Heartache On the Dance Floor,” and was certified gold in August. Regardless of how high his songs do or don’t chart, however, Pardi will keep pulling in more fans the more records he makes. Don’t expect him to play a room as small as House of Blues his next trip through town.
