Anonymous is an ensemble which specializes in singing a capella choral works from the Middle Ages through the Baroque eras, with a focus on Sacred Renaissance polyphony.
The ensemble was formed in 2004 when a group of friends, all Early Music enthusiasts, decided to sing together because of their love for this repertoire.
They became a six-member ensemble in 2005, and have performed in venues across Poland and Europe.
The name refers to the Middle Ages, when Sacred Music was composed by anonymous authors.
