Anonymous 4 are an American female a cappella quartet, based in New York City. Their main performance genre is medieval music, although they have also premiered works by recent composers such as John Tavener and Steve Reich.
The name of the group is a pun on the name used to refer to an anonymous English music theorist of the late 13th century, Anonymous IV, who is the principal source on the two famous composers of the Notre Dame school, Léonin and Pérotin.
Anonymous 4 have performed in cities throughout North America, and have been regulars at major international festivals. They decided to make the 2003-2004 season their last as a full-time recording and touring ensemble, although special projects (such as their Gloryland CD and their "Long Time Traveling" Tour) have continued to bring them together on occasion.
The group collaborated with The Mountain Goats on their 2012 album Transcendental Youth.Continue reading at Wikipedia... Wikipedia content provided under the terms of the Creative Commons BY-SA license
