"I'm choreographing by referencing social moves or places where people dance. I'm interested in how dance can be an expression of intimacy and also that it's the way we attract people, the way we try and impress people. It can be very awkward too."
A visit to Mexico while she was devising Echo Beach gave Sullivan some unexpected insights. "There's a different attitude to dance there. It's a lot to do with sustaining of communities and people coming together regularly to dance and be close to one another.
That really excited me."
Music for Echo Beach has been carefully chosen. "The reaction that people have when a song that they know and love comes on is brilliant."
Although she uses other family moments, including her grandfather teaching her to waltz, Sullivan emphasises Echo Beach is not autobiographical.
"It's about the end of love. I talk about dancing as a way in which you can see something breaking - see a relationship that isn't working anymore. It's also about those first moments of love, the initial excitement of meeting on the dance floor."
