I've just noticed that this due out in the UK at the end of July. I've had it on vinyl since its release and it's a cracker. A solo piano performance and, according to the description at Amazon, it comes with five additional tracks:
"Ogun is extremely proud to present, for the first time on CD, this solo outing by the renowned South African band leader and composer Chris McGregor, recorded live in his adopted homeland of France in 1977. Best known as a member of the Blue Notes and leader of the international big band the Brotherhood of Breath, McGregor rarely recorded solo; his two recitals for the French Musica label have long since disappeared, and In His Good Time has been unavailable for many years. This long-awaited reissue comes directly from the original unedited analogue tapes and boasts a wealth of bonus material, restoring in its entirety the first set of the evening, a continuous performance of original works and arrangements of traditional South African folksongs. Five tracks edited from the second set complete the collection".
