In 1986, four women gathered in a casual setting to sing through a bit of medieval chant. Little did they know they were launching Anonymous 4, an a cappella ensemble that has spanned nearly 30 years, 20 albums, countless concerts and more than a millenium of music.
Today the group announced that the 2015-16 season will be its last together. But this isn't the first time Anonymous 4 has thought about calling it quits. The group bid a similar farewell in 2004.
