She can be a little tricky to spot in the picture above, but the flute section (which she primarily plays in) is located on the right hand side of that picture. Below is a zoomed photo of her playing flute.
The summer concert had a Caribbean theme with some bongo drum pieces, and her years of playing various drums for capoeira groups made her a natural choice for those parts. My favorite was a mombo they played where her drumming was a very significant part of the music and she played very well indeed.
I brought our pocket recorder with us and got quite a nice mp3 file of the event. If you want to hear it and we haven't sent it to you already, drop me an email and I will get you the file to listen to.
