There is some info floating out there on Gilles/Poirier. They have debuted, and I believe a poster said one of their programs was composed for them. I read the title, but don't remember the name. Anyone?
In dance there seem to be three general schools of thought. A. Release your info really early so everyone else will know your music & hopefully keep their hands off. B. Leave no room for negative speculation and debut with an actual performance and as big a bang as you can get. C. Don't tell anyone your music! They might steal it. (Especially if you have somehow miraculously hit on an original SP selection. OTOH, if you're not sure how your SP selection might be received, it might not be bad to announce early in case people care to nudge you in a different direction).
