The acoustic song circle is an opportunity for people to come and share music. No amps, no microphones, just acoustic instruments and the spirit of sharing.
In the spirit of similar circles in the past, the etiquette is that all are welcome to play along with each others songs. BUT if you can't follow them or if its an original the person is still working on, we ask they you hold back. Best to play softly or not at all so we can all hear what's being shared.
