Went to a musical holiday gathering, not exactly a flute circle, but similar.
Had some interesting folks there, including a Biwa player (Japanese stringed instrument, used to back up vocals), a composer who incorporates Japanese instruments into his compositions, shakuhachi, silver flute, and me with world flutes, and a vocalist.
Well, it was midnight before we even had a chance to look at a watch, and I listened to a very moving composition written in remembrance of 9/11, with shakuhachi, cello, keyboards, and violin, that was very moving.
I played transverse bamboo flute, shakuhachi, xiao, and NAF, some with mid eastern tuning, and played a duet with a shakuhachi player, on NAF with mid eastern tuning that was pretty cool.
We also played and sang some carols, some more obscure ones that aren't commonly heard, and it was a very fun gathering.
