“The Led Zeppelin show depends heavily on volume, repetition and drums. It bears some resemblance to the trance music found in Morocco, which is magical in origin and purpose–that is, concerned with the evocation and control of spiritual forces. In Morocco, musicians are also magicians. Gnaoua music is used to drive out evil spirits. The music of Joujouka evokes the God Pan, Pan God of Panic, representing the real magical forces that sweep away the spurious. It is to be remembered that the origin of all the arts–music, painting and writing–is magical and evocative; and that magic is always used to obtain some definite result. In the Led Zeppelin concert, the result aimed at would seem to be the creation of energy in the performers and in the audience. For such magic to succeed, it must tap the sources of magical energy, and this can be dangerous.”
