Sigma

Liricí (lyrics): David Agnew
Ceol agus cóiriú (music and arrangement): Rolf Løvland

"Sigma was originally a piano piece I wrote in a melancholic night during a production I worked on in Bergen. The title, taken from the actual name of the studio, has stayed with us ever since. Not knowing how to include Sigma in the Secret Garden project, Fionnuala suggested adding a sung countermelody, almost Gregorian in style. David Agnew wrote the Irish lyrics. With the lovely voice of the eleven year old Ronan Sugrue and the Irish National Chamber Choir, the recording of Sigma occurred with a very strong spiritual mood."
