At 79, Scott continues to perform, despite suffering a minor heart attack on stage last year. Diagnosed with an hormonal deficiency in his teens that prevented his voice dropping, he turned the abnormality into an otherworldly asset. This handsome collection draws together selections recorded for several labels over five decades for the first time. What stands out is the awesome continuity, the angelic tone that held Marvin and Stevie in thrall, casting its spell into the 21st century. He’s too good to remain a cognoscenti secret.
