Alton Ellis’ entire Studio One catalog of reggae classics is compellingly beautiful, so you know you’re onto a winner here: Emotive tracks like “The Picture Was You,” “Wide World,” and “You Said It Again” are exceptionally rendered, and original first cuts of treasures such as “I’ll Be Waiting” and “Deliver Us” are equally superb. While sister Hortense’s contribution is less crucial, she’s at her best on takes of “Willow Tree,” “People Make the World Go Round,” and “Why Birds Fly,” though a desultory “Breakfast In Bed” spoils an otherwise unblemished collection.
