This is a brief snip of the East Carolina Chamber Choir's performance of Bach's motet "Der Geist hilft" (BWV 226). They did an incredible job on the motet--it was fluid and full of a feeling of dance. What I thought was particularly creative was their placement of the instrumentalists within the choir. We'll be doing this work this year and I expect to use their model when we do it. Enjoy!
