I love CircleSinging & recommend it to everyone.  I mean everyone.  Including the grocery clerk,  my dental hygienist, the guy that just tried to mug me, etc...

 

Circlesinging is improvisational group singing, that's facilitated by a gifted leader.  It's groovy-hipster & spooky-ancient at the same time.  Learn more about it here, and if you're in the Bay Area, come try it out!:
