This is beautiful, but watching unaware of where this troupe is located, I thought these beats are syncopated and it sounds more like an American Drumline in the College marching bands throughout the south, or the New York Radio City Rockettes. Oh, this is Oklahoma, I see. Different beats fused with Irish step style and shoes. LOVE the outcome.
Real proof you don't need fancy lights, sound effects and what not for a powerful performance. Especially loved the advance towards the front of the stage from 0:24 . And darn... I know how hard this is! (I'm a Commission dancer for 10 years now, but nowhere near this level) You all did extremely well!
See how they used the Irish Dance like a drum. You have to watch and listen because you don't know what you're going to miss. Now; you have to ask you're self; how many arrangements could be dune-like this?
