Ola Gjeilo, born in 1978 in Norway, moved to the United States when he was 23 years old to study composition at the Julliard School. He composed this dense and richly textured setting of the Sanctus for the Uranienborg Vokalensemble shortly after he graduated in 2006. Eric Wilson has skillfully captured the magic of the original choral work in this transcription for winds. Ola Gjeilo stated the following regarding Sanctus: ''It's one piece of mine that remains closest to my heart.''
