Forget that Justin Townes Earle’s middle name comes from a revered songwriter and his last name comes from another. When you listen to his songs, you’ll hear a talent who stands on his own. Sure, his voice sometimes betrays his genes, but where dad Steve is rooted in twang — and Texas soil splashed by Celtic rains — Justin is more likely to pluck the banjos of old-timey country or revisit jug-band music, ragtime or Westerberg (The sole cover on his exceptional album, Midnight at the Movies, is the Replacements’ “Can’t Hardly Wait”). Clearly, sounding like his dad is a non-issue. Physically, there’s even less resemblance: Skinny Justin looks more like Hank Williams than Dad.
