The Rainmakers continue a tradition to which relatively few formations lay claim today: spiritual jazz, the heyday of which extended from the mid-1960s to the middle of the following decade. At a time when control algorithms are becoming ever more efficient and the machine is reaching the physical and mental capacity of humans, the craft of Bänz Oester & The Rainmakers is undoubtedly what we need most: they give us this old religion, not as superstitious bigotry, but in the sense of what reconnects us, a precious sense of human belonging, brotherhood and sisterhood. Through their interplay, the musicians tirelessly reaffirm their spiritual claim and their need to free themselves from all forms of constraint. In doing so, they continue a tradition that perhaps still lives on in South Africa today. The presence of Afrika Mkhize and Ayanda Sikade in the quartet is all the more decisive. Together with band leader Bänz Oester and Javier Vercher, they form a conspiratorial unit that cannot be divided by anything or anyone. A formation in which the individual class of all participants is not displayed in an egocentric manner, but is transformed into collective energy.
