With Pharoah Sanders’ blessing, this forthcoming box set, due September 15 on Luaka Bop, will present the definitive, remastered version of Pharoah, his seminal record from 1977, along with two previously unreleased live performances of his masterpiece “Harvest Time." An accompanying 24-page booklet includes a treasure trove of rarely seen photographs, archival materials, interviews with many of the participants, and a conversation with Pharoah himself.
