Each group performs a short set that showcases its strengths. The group is judged on musical ability as well as the overall performance of the group - including choreo - (this years "Down/Forever" should wow the judges).
Break a leg, Octet...that's showbiz talk for "good luck" - unless I've been duped by childhood television...Again.
Below is a performance of Down/Forever that was recorded earlier this year. I can't find the ICCA performance...it may have been removed by the poster for some reason.
"Double your pleasure." LOL! This may be vindication to all the people (including me, unfortunately) who were bitching that the Octet didn't sound great when the '09- '10 Octet were new. Jason Mabie set me straight - the group had one returning member, and it would take time for them to gel. Well, they're sounding pretty awesome these days!
