Sep 18View SourceHi all. I am trying to find a local singing group in Marin (I live in Greenbrae), and the Urban Harmony groups seem to no longer exist. Does anyone happen to know of any groups nearby that focus on current popular music and are open to all? I sang in an a cappella group in college but haven't sung with a group in 15 years or so and am looking to get back into it. Thanks!
