Karma by Delerium

Karma is the ninth studio album by Canadian industrial/electronic music group Delerium. Guest musicians on the album include Sarah McLachlan ("Silence"), Lisa Gerrard ("Forgotten Worlds"), Kristy Thirsk ("Enchanted", "Lamentation", "Wisdom", "'Til The End Of Time"), Jacqui Hunt ("Euphoria (Firefly)"), Greg Reely, and Camille Henderson ("Duende"). The album took around a year to record and assemble. Gregorian chants were recorded especially for the project; according to Bill Leeb, it was less expensive to hire a 30-piece choir, rent a West-Vancouver church, move the equipment and record the chants live than to pay for the rights to sample existing recordings. The duo's collaboration with McLachlan, "Silence", became the band's biggest hit single. The song "Window To Your Soul" is featured in season four of Buffy The Vampire Slayer episode 13 "The I In Team."
