About Incantation

Incantation are a musical group playing traditional tribal and other South American music. The band started in 1981 from a pool of musicians who were, at the time, playing all kinds of different types of music for the (then) Ballet Rambert, based in London. A new ballet was choreographed about political oppression in South America, to the music of Inti-Illimani, the exiled Chilean folk group. The company preferred to use live musicians for performances, and six of the musicians volunteered.
