Janet Cardiff: Spem in Alium August 2, 2008

World-renowned sound artist Janet Cardiff created this sound installation based on 'Spem in Alium' by the English composer Thomas Tallis. Written for a forty-voice choir in 1573, 'Spem in Alium' is one of the most intricate and beautiful compositions of the English Renaissance. In Cardiff's installation, eight groups of five speakers arranged in a large oval allow visitors to experience the choral composition from the vantage of individual performers.
