I just got an email from the BelbinAgosto group, with a link to a Blades on Ice online blurb that announces B/A's Free Dance music:

Coach Igor Shpilband has revealed that Tanith Belbin and her partner, Ben Agosto, will be presenting a Russian Gypsy Dance for their free this season, which will be seen at Skate America in Pittsburgh, October 21-24. "I wanted them to do something different."

According to the blurb, the OD isn't set yet.
