Backhausdance, a contemporary dance company based in Orange County, will perform at the Martha B. Knobel Theater Nov. 2-3. In these audio excerpts, artistic director Jennifer Backhaus explains what makes choreographer Mauro Astolfi’s working process so different from others; what Backhaus looks for when she invites a choreographer to work with her company; how it feels for her company to be collaborating with big-name dance artists, such as Complexions’ co-directors Dwight Rhoden and Desmond Richardson; and then Astolfi talks about working with new dancers and how he developed his movement language.
