There is a web page devoted to all types of music groups all over Wisconsin. It's called Wisconsin Music Groups (catchy name!) and it is at this link: http://my.execpc.com/~regent/
Wisconsin Music Groups is a web site listing of different music groups in the state, maintained by Rich Regent. The list includes community bands, orchestras, choral groups, drum and bugle corps, ensembles, and just about anything else. The list includes information about rehearsals, contacts, and web links. So, if you were looking for a community music group in a certain area of Wisconsin, or you were looking for just a listing of community bands, this site will have a lot of information for you.
I suggest you stop by the Wisconsin Music Groups site and take a quick look. But don't forget about WisconsinCommunityMusic.blogspot.com. Keep visit here as well!
