There are many Early Music groups around, both as supporting organizations and as musicians.  They offer wonderful blends of recorders and other early instruments, especially in the Renaissance and Baroque (and even earlier) eras which many of us know and love.  Here is a sampling of some we are familiar with and events they are planning.  You may also want to check the Concert section for performing groups.
