Sissel Kyrkjebø performing "I Know Him So Well" from the musical Chess, with American singer and actress Judy Kuhn at a concert in Skellefteå, Sweden in 1989. In this duet, two women - Svetlana (Sissel), the Russian chess champion's estranged wife, and Florence (Kuhn), his mistress - express their bittersweet feelings for him and at seeing their relationships fall apart.
Sissel, the international singing sensation and national treasure of Norway, is established as one of the world’s leading crossover sopranos. Her angelic and powerful voice has made Sissel a national institution and she has sung all over the world, selling over ten million solo albums. She has contributed haunting vocal tracks for the soundtrack to Titanic and The Lord of the Rings, and has been performing duets with singers like Charles Aznavour, Andrea Bocelli, Jose Carreras, Placido Domingo, Mario Frangoulis, Josh Groban, Brian May, Neil Sedaka, Bryn Terfel and Russell Watson. In 2005, she was knighted by the King of Norway, as the youngest ever to receive this honour. And in 2006, her album 'The Spirit of the Season' with the Mormon Tabernacle Choir went to number-one on the Billboard Classical Charts, and received a Grammy nomination. A very remarkable voice that only comes once in our lifetime.
