Achillea combine bluesy guitar, deep molasses grooves, and passionate vocals that form a rich tapestry of Nordic atmospheres. Formed by fellow Danes Jens Gad and Helene Horlyck, Achillea base their songs on archaic poems and mythology. Gad, who contributed to Enigma's 1991 global smash "Sadness," builds the music around Horlyck's classically trained voice, resulting in a unique sound that's equal parts precision and spontaneity. Together they created a sophisticated song cycle called The Nine Worlds, which takes the listener on a journey through the different levels of Norse mythology.
