Hello all! I'll be calling a session of challenging contras at a dance weekend next month, and find myself lacking in the aforementioned challenging contras. I want to keep the session balanced, with a mix of dances that are mind-bending or heavily technical as well as some dances that are a step or so below that but that still have something interesting or unique. Would any of you be so kind as to share some of your favorite challenging dances? Thank you in advance!
