You’ve probably never heard of Trey Hensley — unless you went to high school with him in Jonesborough, Tenn. So here’s a tip: The guy’s a very gifted picker and singer. The fact that he’s had guests like Steve Wariner on his pair of independently released albums and opened shows for headliners like Marty Stuart shows he’s respected as a real-deal country traditionalist by folks who take the lineage seriously. And it says a lot that Rob Ickes, one of the world’s premiere Dobro players, is so high on this 20-something talent. He and Hensley are a few harmony parts away from finishing a new album, and according to Ickes, Hensley’s nailed his vocals with nary an overdub. They first worked together when Hensley sang on the stellar new album by Ickes’ bluegrass band Blue Highway, splitting the difference between dignified stoicism and soulfulness in the Merle Haggard mold. Hensley does some hot Tele chicken-pickin’ when he covers Haggard in his shows, and since he started out in bluegrass, he’s no slouch at flat-picking either.
