Back in the ’60s, Ray Price added strings to his trademark shuffle rhythms, which ruffled the feathers of that era’s country purists. His more pop-oriented work helped keep Price at the top of the charts, which is where the great singer and bandleader has always belonged. Now in his 80s, he’s a country music legend whose rich baritone voice would have gained him fame on its own. But it’s Price the bandleader who gave country the distinctive 4/4 shuffle that carried it through the late ’50s and into the ’60s — his rhythmic and textural innovations put him in a class with Duke Ellington and James Brown. His famous band, The Cherokee Cowboys, has featured such performers as Johnny Bush, Buddy Emmons and Roger Miller. Price’s great recordings — 1963’s Night Life comes to mind — sound as fresh as ever, and he remains a compelling, confident performer.
