The Barbershop and Sweet Adelines tradition is alive and well in the Pacific Northwest. There are a variety of choruses, quartets and other groups that can be found here. They have a very well-organized tradition and also have a very large presence on the Internet. Here are some likes to pages relating to these groups.
For more information on these organizations, please follow these links. You'll find links to a lot of the regional groups and choruses here, especially at the Evergreen District site - complete with bios, concert schedules and sometime sound clips. They offer web space to all member groups and are part of the Barbershop Web ring which will link groups all over the world.
