Last week, I had the chance to talk with Betsi Graves, director of Urbanity Dance, and we spent a lot of time talking about the importance of collaborating with artists across various fields. Why would she be the one designing a costume, when Boston is so filled with incredibly talented costume designers? Why pay a high fee to use the rights to a pop song and choreograph a dance to it when you can find a fantastic Boston-based composer who is looking to work with a dance company? Why not collaborate and challenge each other stretch the ways of thinking? To create something greater than you previously imagined you could do?
