For Jiří Kylián, the fascinating aspect of Reich's composition lies in its rhythmical structure - especially in the stylistic device called phasing. It creates a floating underground where the choreography is free to develop independently.
Whereas Kylián customarily considers music as the primary source for his choreographies - meaning that he sets his work on a (existing) musical structure - with Drumming he felt challenged to give unabridged priority to the dance. The result became an exciting and head-on flight of eight female dancers. Falling Angels - 'a piece about our profession' as the choreographer likes to comment on it.
